How is Deezer conndct so shit despite it taking literally years to implement?

I remember the days on the forum asking for a Spotify Connect like feature on Deezer. Despite those days being more than 5 years ago. And yet it still doesn't work at all. If by some miracle it works for more than 3 seconds it's still limited by simple stuff like Play Next not working but most of the time I hear maybe one second of sound coming out of the device before the client app literally gets a stroke. The host I'm trying to connect to sometimes gives this helpful pop-up:

I know this sounds harsh but the problem is that Deezer is full of bugs which I normally accept since I love the UI, the sound quality, the quizzes and end of year stuff. I defended Deezer to everyone calling me crazy for not just using Spotify but issues like these and the lack of a simple bug report + log in the app is just staggering to me.

Here's the video of the app dying when connect gets selected: https://youtube.com/shorts/VEsusaPwjTY?feature=share
