Hello,
I'm not sure when this started, possibly with v5.0 of the Bible app, but my private reading plan keeps disappearing from the Home Screen. In order to get it back, I have to clear data from the Settings app. After 1) clearing data 2) logging in and 3) waiting for the initial sync to complete, the reading plan reappears. However, after a few days, it disappears again without notice.
Bible v5.1.0
Pixel C (Android 6.0.1)
If more info is required, please let me know.
Thanks,
Dan
