Missing videos from 2021 and earlier from iCloud

Hello,

I’ve noticed that all my videos from 2021 and earlier are missing from iCloud Photos. I have checked the “Recently Deleted” folder, and they are not there.

I am using the same iPhone and MacBook that I had back then, and I haven’t changed my Apple ID.I have not knowingly deleted these videos.

Is there any way to recover them from older iCloud backups or archives?

I would really appreciate your help.

Thank you!
