I'm having some issues with permissions with the Experience Builder Editor Widget. A few weeks ago I made this post, which turned out to be me just being a bit of a dingbat...but myself and some testers have noticed some erratic behavior: editing permission changes periodically.
A user can navigate to the application with an account that has permissions, open the Editor widget, and be told the form is read-only. They can re-open the application a short time later and receive no such warning. As I am the only editor of the application I can confirm no changes have been made to anything related to the application within these time windows.
Has anyone else out there experienced similar behavior, or is this gremlins behavior? Clearing chache and using different browsers does not seem to be related. It happens more often to accounts outside of the org, though they have all of the necessary permissions to view the app/map/data.

I suspect it is related to this ongoing issue where the Portal User information does not always pass into Experience Builder.
Interesting. All of the linked discussion is round ExB applications hosted on Enterprise. Mine is AGOL., using no Developer Edition applications. Is there reason to suspect it still applies.
Instinct, mostly. It's an intermittent issue related to user permissions, sounds similar to your problem.
Having the same, it's extremely frustrating for our users..
