My Question or Issue

Dear community, and spotify,

I think spotify connect is not working for volume controlling. 

I have been using spotify with other speakers and web players using spotify sdks, and my devices are appearing correctly to the spotify app of my iphone. However, I can't control the volume for the connected devices from spotify app of my phone. 

About 2 weeks ago, it was working and I could control the volume through my phone, but it suddenly broken without any noticing. 

Please make it clear if this is my own problem or spotify's internal issue.

Somebody please help me to solve this issue... 

Thanks.
