I just launched the app, logged in, then terminated the app, launched it again, and I didn't have to log in again.
Maybe it logs you out after a certain period of time has elapsed or something?
I don't generally use the app, because I can do everything that I need using the web interface, so I don't know if anything has changed in terms of maintaining login sessions.
Maybe it logs you out for security reasons - e.g. so if someone else has access to your phone they can't use your My48 account?
If there has been any change in behaviour recently then maybe it has something to do with this?
You might need to ask 48 support about this.
