I am using a Model Note with Android 6.0.1 and Firmware Build number: 2019-06-13_12-37_2.1.2_23f6dab.
I have connected Google services, download Google Drive and use it as my main Pdfs library. But every day I am being logout from Google services and I am require to login again and again. It is a bit anoying.
There is something I am missing? It is a normal behaviour from google (maybe it has to do with Android version)?
