Hi ​@Peti.H. !

Maybe Deezer is being slow because the cache in the app is full  or some other reason.

For more info take a look in link below

The cache is empty and I installed the apps 3 times.

Also I restarted my mobile as well.

Still frozen and desperatly slow.

Hi ​@Peti.H.! Sorry to hear you're having trouble with Deezer.

To help with the slowness or connection issues, try these steps:

1. Restart the Deezer app by closing it completely and reopening it.
2. Make sure the Deezer app is up to date with the latest version.
3. If none of these work, try uninstalling and reinstalling Deezer from your app store (Google Play Store or App Store).

Hope this helps! Let me know if the issue persists.

Thanj you very much.

My Deezer is working properly now.
