Adding to the 'doesn't happen to me' train 😅
I'm not seeing this issue on Android 16/Baklava either - app version 4.141.0, build 195147. No beta or anything running. I can quit out of the app, wait a few mins and re-enter the app without having to log in.
Were you perhaps added to a new organisation recently with a very low idle timeout or something similar?
Whilst I am a Meraki employee, some of what I post may be opinion (especially architecture!). Others may have better or more efficient ways of doing things, so please learn from everyone!
