I've done some test on the latest version of application (to be sure that nothing has changed

). So the procedure was like that:
1. Application not used for couple of hours, everything in application on (account, MyDrive sync., searching in internet...), Airplane mode on (no internet) - application doesn't start (infinite starting screen)
2. No changes in application, Airplane off (internet by wifi) - normal start of application
3. I've logged out from TomTom account, turn off MyDrive sync and searching, ad exited application (also from memory)
4. Airplane mode on (no internet) - application starts normally (even slightly faster)
5. Airplane mode off (internet by wifi), I've logged into the TomTom account, turned on MyDrive sync etc. and exited application (also from memory)
6. Air plane mode on (no internet) - application starts normally, I've exited application and left phone for night not changing anything in application but I've turn off Airplane mode
7. This morning: Air plane mode on (no internet) - application doesn't start (infinite starting screen).
8. Air plane mode off (internet by wifi) - normal start
I don't have GSM reception in my home (yes, there are such places in Europe so as You can see working off-line navigation has a great sense)
So situation is the same as it was at the beginning of the year. For some time after successful start, application can be started even off-line but just for some time and no one knows how long (my numerous test showed that it can be couple of minutes or hours...)I hope Tomtom
