I can't answer you yet, but I'll try to do the same thing with my iPhone and perhaps I can reproduce the same issue/error. 

I'll let you know. 

@awesomemac thanks!

In my case:

iPhone SE 2020
iOS 17.5.1.
Deezer 10.17.0

I’m afraid that I don’t have any issues.

I can add songs to my favorites (or remove them).

@awesomemac Maybe random error once.

I hope so.

Hello @Zaznetkherson thanks for your post and sorry to hear that you get this random crashes. 

Thank you @awesomemac for your helpful insights.

Indeed we have heard some users with iOS devices having this random crashes as well and our developers have a critical incident even with a low volume of complaints.

There are already some theory's about where the issue is coming from, but we are still analyzing the code.

So with this status of incident, we should see in the coming app updates for iOS the fix to such crashes. 

Nevertheless, I can’t precise a estimate date for the release.

@Leonídia.Deezer Any information about status of fixing?
