I have a question regarding app autostarts. After an update the app optimization process starts, ending with a prompt to restart the optimised apps. After this restart I watched the background start behaviour of my always running apps, normally 11. K-9, Simplex, Signal (all websocket) were starting successfully, Threema-Libre didn't. In total only 8 of 11 apps started.
I rebooted the system again, again only 8 of 11 apps were started, but this time Threema-Libre started successfully, Signal didn't.
How does it all fit together?
