Hi there, @major_groove… I have collaborated on multiple apps that were set to Anyone can edit, and while there are things in the Settings area that people with the link cannot do, they can deploy the app to live and revert to save points. So, that’s how that goes.
Hope this helps.
Best…
Mike
Edit: in case it would be helpful, here are the things that people with the link can’t do in the Settings area. Those folks can’t do anything on the following tabs: App plan, Domain / email, Collaboration, Sub apps, and Versions. On the General tab, they can’t modify the application rights, password protection, the password policy, or the two-factor authentication options. Finally, the Languages, SEO / metatags, and API tabs are wide open to them.
