I believe you need to convert the cookies to the format that BAS understands, and then import them into BAS using a standard method.
Take a look:

I want to make a small script, where I can create a normal account and then go to open.spotify.com and upload a profile image to my account. Simple, wouldn't use it for botting or anything else, just to make accounts and upload images.
As far as I know, for this, the audio isn't required neither DRM Protection nor Widevine, but for some reason I'm still getting the "Playback failed" image at the splash

is there a way to fix this? Also, I'm willing to pay money for any solutions.
