Was improving, now worthless because access has been removed – ABA Annual & Midyear Meetings Review

After not adding much value to the first meeting at which it was used, this app gradually improved. It still had lots of limitations and inaccuracies, but was getting better. But now, as I try to prepare for the midyear meeting, I am suddenly receiving messages saying my access has been removed. I can still see my schedule and all other events, but I can't add or remove events. I tried signing out and back in and also uninstalling and reinstalling, but that didn't help. For how few people use this app and how many flaws it has, if access is going to be an issue too, the ABA should stop wasting energy even trying to provide an app.
