Hi HC,
that is unusual. Is this a new device? Have you installed the latest update, before the first setup?
If you add Deezer to your content, the processing will start too. But usually it doesn't need hours to process Deezer. Deezer is not flawless. Sometimes they have issues as well.
1. Try to submit a log-file to B&O. This will help, if you have to get in touch with BeoCare.
Lift the back-plate. Enter "Diagnostics & Usage" then "Submit"
2. Try a pin-reset (ar. 15 seconds) with a paper-clip on booth devices (Jukebox/Tablet & the Soundheart/Base).
3. Try to log-out from Deezer.
Lift the back-plate. Enter "Add Content" then log-out under Deezer
wait until the new processing is finished
4. Try a second factory reset
Afterwards just log-in to TuneIn, not Deezer
5. Check for a new update. Install latest update, if available.
6. Log-in in Deezer
Again, sometimes it's Deezers fault. In my case, Deezer is today very unstable in Singapore - This is one reason, why want to use my own content with the BS Moment.
