form can not be submitted

form can not be submitted

Hi,

I created a form, and can not submit it. Got an error message: Error occurred, sorry for the inconvenience.
The form has a subform with 54 rows. I do not want to loose data and do not want to create the form again.

Any tip how it can be managed, please?!

By the way...I wanted to initiate a chat from the application, and was surprised, that this is not available anymore?


Have a nice day you all!
George
