I created a custom app version 4.9.0.1, then used the "add version" button to switch to 4.6.4.1, which worked fine. However, now I'd like to switch back to version 4.9.0.1, but it gives an error saying that version already exists. It would be nice not to have to delete the app and recreate it and manually update all the dependencies by being able to revert to a previous version.
