Volume control is out of control

[Fekser]

Hi, I some issues controlling the volume in the BluOS app when the Spotify app is open at the same time. It turns rhe volume up or down at "its own will"

I have the same problem on both my iphone 6 and ipad air. Everything is always updated and running latest firmware and versions of the apps. I have had the problem for 8-9 months.

Anyone else having the same problems and may know a solution?
