Try this quick fix:
1. Tap the Group Details Icon (second from the left at the bottom of the screen) and then tap ‘Details’. From here you’ll see three headings: Previous, Next Gathering and Upcoming. Tap on ‘Previous’ to see completed weeks.
2. Tap the week you’d like to return to, then tap the red ‘Did you not meet?’ button. A pop-up menu will give you the option to adjust your study week. Tap ‘Adjust study’ and the app will reset to the selected week.
You may need to log out and back in for the change to take place: Tap the Profile Icon on the bottom right of your screen, then ‘Settings’. Then tap the icon on the top right and select ‘Log Out’. Sign back in and make sure you select the right Group.
