I've been using Deliveries for years on my Android phone and on my Chromebook. Synchronization, logged in through Google, has always worked fine - until a few days ago.
Now, when I try to synchronize on my Chromebook, I get an error message "Google Sync failed! Please reconfigure your account." But when I go to Settings > Synchronization, the Synchronization switch is greyed out, and when I click on the Google button to try to reconfigure, the app blinks but nothing else happens. (Note: now I'm getting "Unknown Sync failed!")
Synchronization still works fine on my Android phone, which also uses my Google account for synchronizing.
How do I fix this? Do I have to create a Deliveries account and switch both apps to use that? And if I do, is there any way to preserve my data?
Thanks in advance for any assistance!
