Exactly the same issue unfortunately. Hope Deezer will fix that quick 

Hi @Tessa Merino Osoro @Apow35 are you still experiencing problems with Deezer on your Apple watch?
Thanks

@Jaime.Deezer yes I still have the same problem unfortunately. 

Still have too

At old watch SE have sometimes same issue

We have tested on our side with Apple watch 10 and it works fine without crashing.
Could you please try the following troubleshooting and let me know if if works?:

• reinstall the Deezer app
• Restart your Apple watch by pressing and holding both the Digital Crown and side button until the Apple logo appears and try again

Thanks

I have exactly the same problem and have tried uninstalling the application on my phone and on my Apple watch as well as restarting my Apple watch but the problem persists. As soon as I press ‘playlist’ or ‘download’ the app crashes.

At SE crush sometimes when open playlist sometimes when playing, but most popular situation - music autopause
