Sony xperia z3 compact
My Question or Issue
Im using Spotify (currently version 220.127.116.117) on a Sony Xperia Z3 compact .
This old phone do not have any SIM card, im using it for music and connect it by Wifi only once a week.
I have a problem for twice by now : I synchronize my main playlist on day 1 by wifi on the sd card, then i disable the the network and turn the app to offline mode. For days after, everything is working. After 7-10 days, or after a reboot , or after an uptade, my playlist is no longer available offline ! Even if the files (in sd/android/data/com.spotify.android) are still there !
I have to sync again , and with more than 1000 track, unless to say that is extremely disapointing !
What is the problem behind it ? What is the solution ?
