Spotify not logging into the correct Facebook account.

[RichardForShort]

I’m trying to log into my account on another phone. However, there are two different Facebook accounts logged into the same phone and no matter what I do it only lets me log into the account under the wrong Facebook. So it’s my girls friends Facebook and mine, but it only will Log into hers. I’ve tried removing her Facebook account from the app but it still logs into hers instead of mine. Any solutions?
