I had the same issue on my 2019 RAM 1500 Laramie with 12" screen after disconnecting the battery to change it --> no backup camera, no surround camera, no passenger side controls for heated seat, hard buttons for hot / cold not working (temperature set on max / min). I drove it for 30 minutes and it did not correct the problem. I tried soft reset and it didn't work it. After leaving it for a couple of hours, it all worked again. My earlier call to Uconnect said I had to take it to the dealer to get the App version up graded to QR 40.1 or later (current version was LR 34.31. Agreed that Uconnect should tell folks to wait over night and then check things out. Thanks to all who post to the forum as it's difficult to get good info from Uconnect or the dealer.
