Deezer does not work via Chromecast

After 7 years I've run out of patience and just signed up for Tidal. The UI and way it works is going to take some getting used to, but I now get the HiFi sound i signed up for on all of my systems. 

I’ve had Deezer for 3 months free there’s no way I can even consider subscribing it’s nothing but a nightmare it won’t connect to cromecast the app well weres a simple song history list I’ve never come across a music app so poorly designed and does not function crashes my phone and blasted my Harmon speakers throwing in 500 wats of music out uncontrollable volumes issue’s vie phone app Harmon app nearly o never again 

There is this issue from one year.

At this moment chromecast with deezer is a nightmare

Same problem. I can no longer chromecast to my Naim Nova and mu-so systems whilst it works fine with Spotify or Tunein. 

No communication from Deezer, appalling customer service. 

I had the same problem both with an harman kardon Omni-20 and an HK soundbar. I found two solutions... First starting deezer and next from Google home select casting from the chromecast device works.

But even better, I found that when the speaker is in a group with a regular chromecast, selecting the group in deezer works flawless. I have an old chromecast audio now which is in my wifi netwerk but not connected to a speaker. I Just create a group in Google home combining this dummy chromecast with a speaker and everything works fine. I have multiple group now each containing this dummy WORKS…

By the way, my wife uses Spotify which has the exact same problem when using chromecast.
