How to maximize 2T of iCloud extra storage
I have been paying for 2T of iCloud extra storage, but it seems like I am hardly utilizing any. I use Gmail as my primary email account, and do not use my iCloud account. My Google account is 99% full and I would like to avoid buying extra storage in Google. Can I revert to using the Mail app on my iPhone 14 to use Gmail? I forget what I need to do in settings. Would this alleviate storage in Gmail, or do I not understand anything? 90% of my Google storage is Photos....Thank you.
iPhone 14, iOS 17
