Aaand another bug. All of a sudden the Remote app's reported "Time remaining" dropped by over an hour to exactly 5 hours 0 minutes and then disappeared. Phone reboot = nada. Until now it was correct. The car still displays the correct time (well I don't know if it's fully correct, but it's consistent). Restarted charging session and the app is now stuck at 5 hours 0 minutes while the car is still 'correct'. All the other data seem right so it's not some random interwebs connection issue. Oh wait, the app is back to correct now. WTF.
