This is what the support team told me in response to my bug report:
"Hello,
The following list below contains suggestions for how to resolve updating/syncing problems:
--Turn off the mobile device completely, wait a couple of minutes, then turn it on again. Rebooting will reset the app.
--Delete the app, wait a few hours and then download it from the App Store or the Play Store. The wait time is crucial to ensure that the old version isn't pulled back up.
--Go to the More Menu > Settings > Refresh Data. This will kick-start the automatic updates as well.
One of the options above should reset the app. If the problem persists, please let us know.
Thank you for your time and patience,
Sincerely,
The Response Team"
