I am a grapheneos user. I have to use instagram and facebook for work reasons. I activate always-on/ block connections without a proxy. Since they are in separate profiles, they are completely sandboxed from my personal apps. However, my question is when switch users (unlike logging out in dekstop), the apps from my second profile stay active and connected to internet or not. There was even an post saying that cross-profile notifications are possible. So, I am asking to learn if it is possible for those invasive apps to follow me through IP addresses of the two different profiles.
Thanks for your help.
