Ape Apps

I’m using an iPad. I have the most recent version. When I try to start a city in a region it goes to a black screen with only the lander visible. The words “save in progress” go across from top to bottom. I can’t exit without shutting down the whole game. I can play a single city map, but there are glitches there too. I have to watch the woodcutter or he just stops. Vehicles seem to just disappear completely and sometimes they randomly appear without me buying them.
I appreciate all your hard work! Hopefully this will get worked out. Thank you! I’ve attached screenshots.

I don't know what wood cutters are, but if vehicles are moving, especially on a single map, they usually teleport to their destination rather than actually moving to reduce the lag due to path finding. Don't know about your regional problem, but yeah, disappearing and re-appearing of vehicles in single map is intended to be so

I know vehicles teleport, these are disappearing completely. Forever. The woodcutter is what harvests the trees in one map. They completely stop working unless I’m staring at them, that’s not how they usually work. I’ve been playing this game for over a year and this is new. I’m definitely more worried about the region not working. Thank you for trying to help, I appreciate it.
