Permanently deleting photos INCREASED my available storage
Apples support gave me the following steps to fix this problem and it gave me 20GB of available storage. I was concerned about my photos though it looks like it just moved all of them to the iCloud. Not sure I have questions about this.
general > transfer or reset> reset > reset all settings
i had to log back into my wifi and change some settings though not sure what else has changed. Please advise.
iPhone 7, iOS 15
