I’m assuming that because the A6 is being controlled by the Eversolo app on my mobile, A continuous wifi connection is required, even when playing from the internal storage.
I’ve never tried playing music by controlling it from the front touchscreen on the A6, only from the Eversolo app on my mobile.
Maybe I’ll try switching off the app on my phone and use the touchscreen in the A6 instead and see if it still drops out. 
Nope, the app sends a ‘playlist’ to the A6 which then gets the songs directly from Qobuz or the storage etc.
You can start an album playing and then close the app and it will continue playing.
Had a problem with Qobuz today. Had a message on the Eversolo saying “server error” then all my favourite albums and tracks disappeared.
Tried logging out of Qobuz then rebooting the streamer then logging in again but still no favourites.
Then looked at “account” and discovered the account name was something or someone else, despite that I’d used my email and password to log in.
Tried logging out, rebooting my phone and logging in again and the account name was different again (but not mine)
Have I been hacked or something?
Can you log in?
If so, change your password!!
Cannot find my account details. In Settings my username appears but no “my account”
How do you log in, then?
Subscription expired?
Maybe PM me the unknown account details as they might be mine as I logged in on my account at one of your bakeoffs when you first got the streamer.
Also, try logging in using a web browser.
Login at qobuz.com
Click forgotten password and reset your password
Login on the Eversolo with the new password
Had to go out for a couple of hours; logged in when I got home and everything was back to normal. Must have been a server barf at Qobuz HQ.
Changed my password.
Cheers for the responses guys! 
I’ve had some weird shit with QoBuz - I had a period where it would just randomly add favourite songs (but not albums) - sorted itself out after several months but felt very much like an account hack to me.
Yep, this is the second time something weird has happened Ben, I started this thread the first time.
Although the symptoms were different, on both occasions it seemed to reset after a couple of hours.
