Random errors since about 1-2 weeks

Which OS are your using: iOS or Android? And both the most recent release?

Android. Most recent, yes.

But also in the web player, like I said. I use that a lot more, so I get the error more often there.

In the browser console, it says for example (I removed query params since it looks like you might send potentially sensitive data there):

f-cdnt-stream.dzcdn.net/media/1/3/7/9/f/1852672447/79fe1ffac237a89f12539acfa02bcbc0.mp3

           Failed to load resource: the server responded with a status of 618 ()

Could you please share a screenshot of the error message in order to investigate.
Thanks

Will do if it happens again. It's possible that it happened because I'm using Brave. I recently turned off tracking and ad blocking for Deezer, maybe it'll work now.

(But if it does, then the Deezer web app doesn't work correctly in my opinion. Because blocking tracking and ads shouldn't stop the player from working. At least for paying members. Although, if I recall correctly, you don't offer an ad supported free option anyway.)
