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.
