So my problem is that I wanted to change the subscription billing date to be in sync with my payday. I followed the instructions on Spotify website and stopped my premium subscription for some days. I signed up again on 26th so that it would be the date when I would be charged for my monthy subscription. Instead, Spotify started to take money on the 15th! Apparently the help info on the website is wrong and thus should be removed! This and other translations: https://support.spotify.com/se/account_payment_help/payment_help/change-subscription-renewal-date/
What is the correct way to change the date of billing?
