Hello Geri1982,
Information about the My Photo Stream shutdown - Apple Support.
Yes, My Photo Stream is being shutdown. July 26, 2023 will be the last day. Apple themselves have said the following:
"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 toggled on for all of your Apple devices and you will be all set. Live photos, photos, and videos can all be safely stored, accessed, and synced across all of your devices via iCloud Photos.
