After adding tasks it gets stuck in a cycle of attempting to sync. Even after waiting for 45 minutes it is still stuck. If I log out and back in I have lost the tasks I have added. After doing so, it will sync for a few minutes, but then get stuck again.
This has happened to me too. Both at creation and at deletion. It started about the same time as for you. BTW, I’m a single user so my issue is not about synching with others, just synching my tasks beteween my interface and the system)
At creation, tasks are greyed and disappear when i refresh the page.
To play it safe, I now have to refresh the page after each interaction with a task, which wastes loads of time and creates frustration.
I just realised one task I have forgotten about for several days as it disappeared during a refresh. Maybe I’ll play it even safer and create tasks in Google to then manage them in TaskBoard?
