I've been monitoring this bug since last month. In August, I would find from time to time, that the July Spending Plan would suddenly show the !, and that my Planned Spending categories that had been completed with funds released had all reverted to 0. So that instead of showing the Planned Spend balanced at say $-2300, it now shows that I overspent $-2300. I noticed (or thought) this would happen after an update to the web app.
Now today, the same thing has happened but this time it is August (the last month again). Exactly the same thing. And it shows the same in different browsers and the mobile app as well. We've also not had an update so far this week, so I don't think it has to do with that.
Has anyone else seen this behavior? Could it have anything to do with auto release? I turned it off.
I've sent in my logs and a screenshot to Feedback.
