Overview
Restoring a Canvas App to a previous version is easy to do with a few simple steps. Microsoft stores every version of your app for up to the last six months. Each version of your app will be stored in the Power Apps release that it was created in.
This flexibility allows you to restore apps when necessary if issues arise, or if you want look at previous version of the app before changes have been made or dropped.
