Survey ID not found

Hello,
A deployed survey is having repeated issues loading in web browers (Chrome, Safari, Edge), but not mobile android and iPhones. Torubleshooting has been tried from several computer devices.

The project is active and the link is correct. I am the creator. It has not been redeployed yet as to not change data collection.

The error is the following: “Loading error. Survey with this ID not found”.

Please help is assesing the issue.
Thank you,

Welcome to the community, @Nico_olas! Have you made any successful submissions to the project either through the Collect Android App or web form before you faced this issue? Or have you just deployed this project?

BTW, have you also validated your XLSForm through this online validator to see if there are any syntax issues that is causing this loading error?

I have had many succesful responses over the last 2 months using the web form. We are not using the Collect App as a method.
The online validator showns some warnings about labels, but no errors. (see screenshot):

Submissions through moile phones are being received succesfully.
Thank you for the assistance.

This is an issue of your incorrect language configuration. See. please: Loading Error As A Result of Language Removal - #2 by Kal_Lam

Thank you, but I don’t understand your suggestion. I followed your link, but language is not an issue for my survey. Responses are being collected just fine in both languages through mobiles, but not computers.

Sorry, the warning shows a language issue. Not all necessary elements are defined for all languages (or not consistently). For ex. there are two guidance_hint::language() columns missing. There are also language inconsistencies for choices, hints etc.
