Hi @awsteenoh !

You can’t play music on phone and desktop in same time .

With Deezer Premium and Deezer Student, you can link up to three devices to your account. It's important to note that you can only play music on one of the three devices at any one time. These subscription offers are designed for individual users, not multiple users or families.

I’m not trying to play music on the desktop and phone app at the same time.

Like I explained, I am trying to select a song from the iOS app to be played on my desktop app which is on the same wifi and is connected to my speakers. 

To explain it another way, I am using the phone as a “remote”. 

Again, not trying to play two songs at the same time or something like that. And Deezer is only on two of my devices so that’s also not the issue.

I will start another thread if I do not get an appropriate answer because this issue is not “solved” like the thread now implies.

When you use phone like the remote control ,then you need in Deezer Connect select a device from which your music will play .

Did you @awsteenoh do that ?

That is what caused the error.

Step 1: play music on phone

Step 2: select speaker/device (my laptop via the deskop app)

Step 3: error or freezing or plays one song then when you try to change it it freezes

To clarify: step 2 is done via the phone so I select the output device via the iOS app. Hopefully that is clear now
