It's a mess. I add new tasks and tag them. But they will randomly disappear, reappear. And the tags will disappear. Editing and adding them back in doesn't help because once a tag disappears you can't add it back in again. Disappearing tasks is the worst because there's no warning. They're just gone. They're not listed as complete, they just disappear. Sometimes they'll come back but sometimes I have to re-enter them...assuming I remember. I pay for this app, so the fact that the basic functionality of keeping my list intact is random and spotty is unacceptable. It may have something to do with syncing... no idea. But either way, I'm going to use another app because I just don't trust it anymore. These errors seem to be recent, like in the last 3 months.
