FORM is not working/ Submmiting

Question:
FORM is not working/submmiting the info in WIX Studio

This is my scenario:
I have designed a website on my own account and once finished and everything worked fine I transfered the website to my client’s account.
Once there, I reassigned a Premium plan / Domain to the new studio website - I had to upgrade the plan because old website (just a landing page) was a wix editor website.

The problems started here, because the main url was pointing for the old website, even though url\page was pointing correctly. This lasted several days, I created a support request, wix support kept saying everything was working on their side and they couldn’t replicate the issue. Eventually without anyone having done anything this stopped happening.

However, alongside with that issue, Forms and CMS dynamic items weren’t working properly either.
When I access the page the first time, the form does not load.
I refresh the page, the form is then displayed. I fill in all the fields, but when I click submit button, it displays a message saying "It wasn’t possible to send your form. Please try again later " and sometimes it doesn’t even show this message.

I have request support and it has been handled by 3 or 4 different people that always reply the same way:
"I have not been able to replicate the issue, try the following steps:

  • Opening in private (Incognito) browsing mode
  • Disabling add-ons (extensions)
  • Disabling anti-virus software
  • Different computer
  • Different internet connection"

Which I have tried every single one.

I tried seeing dev tools and there’s this error “submissions”:

So my question is: did anyone already have this issue? Is it possible this is due to some kind of synchronisation or anyone has an idea on what may be causing it?
Also this does not happen only in my pc/environment as I have many users around the country complaining about the Form.

Any help is much appreciated!

This issue appears to be rooted in a combination of transfer-related misconfigurations and potential connectivity or cache conflicts caused during the migration and reassignment process.

Yes, that’s where I’m leaning also.
In terms of configurations, support team has told me that they validated everything and all seems correctly configured - I have also checked this and looks all nice.

Regarding connectivity, what could be the fix? I have tried a different wi-fi, a different computer with different OS, I have tried in mobile with mobile network… I mean, doesn’t look like cache to me.
Also, the fact that this is affecting users in different cities also seems suspicious to me. I have though maybe a sync on some specific server… does this make sense?

Your thinking is on the right track—if users in different locations are experiencing the issue, it likely points to something broader than individual device or network issues.
