Hi,

We've been measuring our form submissions through Google Tag Manager. We did this by adding an event in JS in the Post-submit HTML  like this:

<script>
window.dataLayer = window.dataLayer || [];
window.dataLayer.push({'event':'leadform_submission'});
</script>

This method suddenly stopped working and can't find the reason.

It's not a GTM issue, I've tested a simple JS like this:

<script>
alert("thanks");
</script>

and it won't run either.

What could cause JS not to run in this section anymore?

Thanks

Thanks, Paul, that's a tremendous help, at least I know now where the problem is coming from!

Is there a new, recommended way to measure form submissions, or it is just not supported anymore and that's that?

I am in the exact same boat, I thought I was going crazy for a little bit.

Did you figure out a solution to that? 

I am about to try putting it in the footer

.

Edit 

I ended up redirecting to a thank you page

Following this - any updates on a fix or a new recommended method to measure form submissions?

No solution yet, but I did confirm that the new international-friendly form block also breaks Zapier integrations if you are passing hidden fields.

It is possible to detect the events with an ajax listener, but that seems fragile and likely to break with a later deployment.

Seems like something they should have tested...

I (was) using it for passing user-provided data for enhanced conversions tracking in Google Ads, this is now broken as I had to revert to redirect and track a thank-you page. Squarespace should prioritize this and make an urgent hot fix in my opinion, it is a bit embarrassing.

Our form submissions have also been breaking.  We've lost many potential customers and now we have to redo our forms, and upgrade to "business" just to add web leads into Salesforce.   There was no warning of this change.   Squarespace customer support was also unable to give us direction on what had happened.

I have created a video about this and posted the code on GitHub(https://github.com/sorcamarian/squarespace-tricks/tree/main/Forms)
