I have discovered through trial and error with mine that the IBUS app seems to want to start first. If it doesn't it's glitchy. Nice thing is that you can program in the app for autostart of the app you would like as your start up app to start right after the IBUS app. You can even program a second one to start after the first programmed to start after the IBUS.

Now if I could just figure out why the cluster and heating and cooling control show in C instead of F I'd be happy. No matter what I do seems to get it to change. It shows everything in the IBUS app in F. I did a factory reset on the Avin and the IBUS app when the problem first happened, but it didn't fix it. Maybe an email to the IBUS guy is in order.
