I find it ridiculous that there are some functions that are available in the Web Editor that are not available in PA Studio -- one of them is being able to rollback to a previous version. While in some cases, this is workable, the rollback function is often not.
My main problem here is that when I edit an app in PowerApps, decide that whatever I was trying to do was not working, and undoing the changes is just inconvenient -- I just want to be able to rollback to a version I want. So, I usually just go to File > Share and that opens a web browser window. Then, on that new window, click on Versions. I find the version I want to rollback to and clickon its corresponding Restore button. A dialog box appears and I click the Restore button. Guess what happens? I get this message -- "Restore failed. 'Whatever App I'm Editing Right Now' is locked by Name (User Email)". Even when I close PA Studio, it still doesn't allow me rollback. I have to wait for god knows how long for it to unlock just so I can rollback.
So, PA Team -- Do this? I mean, it wouldn't be much of a stretch. PA Studio, if I read what your support team had posted a while ago, is just IE11.
EDIT: Forgot to remove personal information from the error message.
By design, versioning options will always reside in the cloud, which is why you are redirected there when using the desktop Studio app to share or to review versions (let me know if I'm misunderstanding your ask).
On the other hand, the error message you mentioned makes me think you may have an issue we should look into (which is 'not' by design). Would you be willing to open a support ticket? You can do that from the top navigation "Support" link of the community. If you have an urgent situation, please don't hesitate to private message me so we can connect directly.
Thank you for your patience while we determine what might be causing that issue for you.
