Spotify Playback SDK - Stuck devices in Connect

[Sawy7]

Hi!

My problem is really simple, but I have not been able to either find a solution or reach anyone at Spotify, who would be able to resolve this for me. Basically I was toying with Spotify Playback API a few weeks back and with each launch of my test app, it spawned new device in my Spotify Connect menu. That is the menu, where you would find your smart speakers, TVs etc. However, these devices are still there, a long time since I tried running my app. They have not timed out.

So my question to you is: how do I go about removing these devices from my Spotify Connect? I've tried removing logging out everywhere and removing API access to every random service to no avail.

See this screenshot:

Thanks!
