Update Google play subscription to a different Google account ?

[#1]

I have Google account "A" and want to switch payment method to Google account "B" or even just manually add my card to Spotify. However when I hit 'manage subscription' it just tells me I need to log in to Google account "A" which I have tried. It still repeats the message. I then tried just opening Google play and cancelling the subscription in Google play. That cancelled it, however it still will not let me select a new payment method. It just says I have to manage is through Google play with account "A" and then tells me to sign into "A".

Hey there, 

Thanks for getting in touch about this and welcome to the Community!

Keep in mind that you won't be able to change your payment method if your subscription is still active (even if you've already canceled it). In this case, if you'd like to change it, you'd need to wait for your account to revert to the free service and then you'll be able to re-subscribe with a different one. 

Hope this helps. If you need a hand with anything else, the Community is here for you.
