I have been on Photography Plan for years (monthly payment), changed last month to yearly payment (paid) and then bought 1 year of the same plan through a reseller. The code was accepted and everything seems fine.
But there is no confirmation in my account that the code is actually active and will be used: next year payment hasn't changed (2022) and it's still associated to my payment card.
How can I verify that the code for 1 year is really active and taken into account?
I see you have an active Photography subscription under the same ID as with forums. You are being charged on your card for that subscription and there is no code associated with it. Did you use the same email address to activate the code?
