Why am I receiving notices that iCloud will no longer store my photos

Hello SusZn,

Only My Photo Stream is going. It will shutting down July 26th, 2023 - Information about the My Photo Stream shutdown - Apple Support.

Apple has said:

"Moving forward, iCloud Photos is the best way to keep the photos and videos you take up to date across all your devices and safely stored in iCloud. If you already have iCloud Photos enabled on all of your devices, you don't need to do anything else — your photos already sync to iCloud. To check, on your iPhone or iPad, go to Settings > your name > iCloud. On your Mac, choose Apple menu  > System Settings, click your name, then click iCloud. Make sure that it says "On" next to Photos on each of your devices."

Make sure this setting is on for all of your Apple devices and your photos will be safe!
