Why do GoHighLevel survey and lead forms freeze on iPhone Safari, and how do you fix it?

Quick Answer: When HighLevel forms are embedded as third-party popup scripts, iOS Safari's default 'Block Pop-ups' setting halts cross-origin window/modal triggers while the script locks the background scroll, freezing the page. Fix it by switching the form integration to Standard Inline Embed inside a native site modal wrapper, and mapping a custom CNAME to avoid cross-domain ITP drops.

Why GoHighLevel Survey and Lead Forms Freeze on iOS Safari and How to Fix It with Inline Embeds and CNAMEs

What Usually Goes Wrong
  • When mobile visitors open an external website embedding a GoHighLevel survey or form as a 'Popup' or 'Overlay', tapping the trigger button causes the entire page to freeze on iOS.
  • No error message is shown, the form never appears, and the user cannot scroll or interact with the screen.
  • This happens because Safari's factory-default 'Block Pop-ups' security feature blocks cross-origin popup scripts (running from msgsndr.com or leadconnectorhq.com), while the embed script's transparent overlay intercepts touch events and locks parent page scrolling.
The Simple Fix in GoHighLevel
  • Replace the third-party popup script with an inline iframe embedded inside your site's native container, and route it through a custom domain CNAME.
  • First, in HighLevel go to Sites -> Surveys (or Forms) -> Integrate and select 'Standard' (Inline Embed) rather than 'Popup'.
  • Second, if you need a popup modal, place that static iframe inside your website's native HTML modal wrapper, Webflow lightbox, or WordPress popup block on your own domain so Safari treats it as local first-party markup rather than an untrusted popup.
  • Third, connect a custom domain CNAME (e.g. forms.yourdomain.com) so Safari's Intelligent Tracking Prevention (ITP) doesn't suppress form cookies or submission payloads.

Where to Click in GoHighLevel

Step Where to Click in GHL What to Do
Step 1 Sites -> Surveys In HighLevel, open Sites -> Surveys (or Forms) -> click 'Integrate' in the top-right corner. Instead of choosing 'Popup' or 'Overlay', select 'Standard' to copy the responsive inline <iframe> code.
Step 2 Automation -> Workflows -> + Create Workflow If your site layout requires a button click to open the form, paste the inline iframe inside your site's native HTML modal wrapper, Webflow lightbox, or WordPress popup block. Because the modal container lives on your own website domain, iOS Safari triggers it natively without activating its third-party popup blocker.
Step 3 In HighLevel Settings -> Domains In HighLevel Settings -> Domains, add a dedicated subdomain (such as forms.yourcompany.com) and point its CNAME record to msgsndr.com. Serving the form assets from your brand's own subdomain prevents Safari ITP privacy filters from flagging cross-site tracker frames.

  2. STEP 2
    Wrap in a Native Website Modal (If You Want a Popup Button): If your site layout requires a button click to open the form, paste the inline iframe inside your site's native HTML modal wrapper, Webflow lightbox, or WordPress popup block. Because the modal container lives on your own website domain, iOS Safari triggers it natively without activating its third-party popup blocker.
  3. STEP 3
    Bind a Custom Subdomain CNAME: In HighLevel Settings -> Domains, add a dedicated subdomain (such as forms.yourcompany.com) and point its CNAME record to msgsndr.com. Serving the form assets from your brand's own subdomain prevents Safari ITP privacy filters from flagging cross-site tracker frames.

Audit and update our GoHighLevel survey embed for iOS Safari compatibility:
1. Reconfigure the survey integration from 'Popup' or 'Overlay' script mode to 'Standard' (Inline iframe Embed) to prevent iOS Safari's default Block Pop-ups security trigger.
2. If a click-to-open modal is required, nest the static inline iframe inside our website's first-party HTML dialog or theme modal container rather than relying on cross-domain window.open calls.
3. Configure a custom subdomain CNAME (e.g., forms.ourdomain.com -> msgsndr.com) and assign it to the survey sub-account to bypass Safari ITP cross-site tracking drops.

Why is my GoHighLevel Inbound Webhook not creating or updating contacts?

Fetch a real sample request inside your Inbound Webhook Trigger (never use the 'Test Workflow' button), add a native Format Data -> Format Phone Number (E.164) step first, and map the formatted phone and email into Create/Update Contact.

How do you stop iPhone Live Voicemail from breaking GoHighLevel Missed-Call Text-Back?

Why is GoHighLevel still sending messages after a customer replies?

The native 'Stop on Response' toggle only stops the specific workflow that sent the message—it never removes leads from overlapping nurture or blast campaigns. Fix it by building a dedicated global Safety Net workflow triggered on Customer Replied with an explicit Remove from Workflow action.
