iphone photos will not back up and I have enough storage
I got a message "Not Enough iCloud Storage" when I went to back up by photos on my iPhone. I clicked on "Manage" and bought the 2TB subscription so I should now have plenty of storage. Still getting the same message though when I try to back up. If I click on "Manage" it just takes me to my iCloud Storage setting where it shows I have used 49 GB of 2 TB of available storage. I am going in circles and don't know how to fix this. I've turned my phone on and off twice but that didn't help either. Please advise! I am stuck.
iPhone SE, iOS 15
