How to Remove spotify account from roku credentials

[user-removed]

Does anybody know how to remove my spotify account from roku accounts? I used sign out everywhere and it worked but when I opened it I still had my account information on the tv. It didn't completely remove unless I removed my account directly from the tv, which is an issue because my account could possibly be connected to another tv that I don't have access to, in another city, and I don't want my stuff getting messed up. I don't know why spotify accounts automatically connects to roku credentials that are on Roku tv devices, but they need to remove that.
