Hi,
I have added a user to a form and given him the rights to edit submissions. But when that user is trying to edit the form, following message is displayed:
"Oops, this form doesn’t exist (anymore). Most likely the owner of the form has deleted it, archived it, or disabled it. Please contact the form’s owner to confirm. Detailed error: Form with ID a3cfbbTEGc8KNqdfRZJSib not found in /formList. "
Whereas I (owner) have not deleted anything - neither form nor the submission. Also, when I am trying to edit the same submission, it is working well.
Would you mind requesting your colleague to check them now. Your colleague should be able to edit the submissions now. As a solution i simply provided your colleague an add submission permission and it worked.
