HP TouchSmart300 with an AMD Athlon II X3 400e, iPhone Xs and iPad Pro 12.9 5th gen
Windows 7 Professional and iOS 15.4.1
Lately I've noticed that while I'm playing music on my phone and also have the desktop version open, it doesn't show up that I'm playing the music even though they are connected with each other. Same goes for the other way around and even when I try to switch between iPad and iPhone. When I try to switch the device the music is playing on, it completely stops with no song showing up on either device (as if you've just opened Spotify for the first time). I've tried a simple restart and a clean install on all devices.
Now the pc I use is quite old with older drivers, however I've never experienced an issue with the desktop app before, nor between iPad and iPhone.
Any idea on how to fix this?
