Device regullary logouts and removes local cache

[jorgosw]

Hi,

I have a problem, I have a tablet with Android 7.1 mount in my car. It's almost all the time connected to the internet, but because sometimes I go for trips through mountains or villages with low internet connection i have local cache on internal memory (about 600 songs). At least twice a week device logs off from my account and I need internet to reconect, the local cache is deleted. Downloading this amount of data from cellural phone is kind of reckless... Yes I use my account on different devices (Desktop, phone). Only phone uses local cache as well, other devices are using only "streaming" option with no local cache. All devices are always connected to the internet (including cellural phone). So actually the only device that I need to be able to work offline is not able. Can you please help me with that?
