Bug: Manual Sort Doesn't Stick – Facebook Groups Review

Bug: If you manually sort your groups within the Favorites list, it reverts back to alphabetical sort if you re-enter the Edit screen or exit and re-launch the app. Annoying. What's further annoying is that this bug has been around for at least two (2) revision updates! I've sent them bug reports. My reports go unresponded and obviously the bug goes unfixed. My revision is the latest, as of May 12, 2016.
