Quite often the left side tasks are out of sync. They've often refreshed only when I clicked on them, viewing them. There was also a case it was a deleted task, and only after opening it I got a notification it was deleted, and the whole screen refreshed, and the item was removed. (Perhaps instead it could've had a deleted status color, and/or have been crossed out, maybe?) Also, occasionally I leave a list open, and find it is out of sync. I've added an empty list shortcut, to go to and return from, to refresh the list, as a workaround. [Also, after typing most of this up, I clicked Create Post, and I was redirected to log in. Then, after all that, all that I've typed was deleted...]
