I went back and selected ‘default’ icon in the settings and the duplicate one was removed.

Looks great. Suggest that the backup file have a unique name so it is not confused with the Boost for Reddit backup.

Revert to v6.2.19 and disable auto update - still works great on Android 13/One UI 5.1.

Good info, thanks.
