Not sure when this exactly started happening, definitely after 4.0 and before 4.0.4. After starting DTTG on my iPad, DTTG briefly appears and crashes. Starting it 4 times in a row would make it work. Since a few days ago, it has taken more than 4 times, and this morning, no amount of relaunching helped. Closing all other apps did nothing. But restarting the iPad made it work on the first try, and reproducibly so. I’m now on 4.0.5. The same version has no problems on my iPhone 16 Pro. My iPad is rather old, a 2019 iPad Air. Maybe this is a RAM issue? The good news is that I’m waiting for an iPad Pro with M5 being delivered, so this problem should go away. But curious whether anyone else has experienced this (all my devices always on latest DTTG and latest iOS).
