Icloud photos missing.
Hi, i recently upgraded my phone from a 5s to a 2020se. I Backed up my 5s before putting my sim into the new phone and using the phone swap where it backs up from the old phone to the new one by leaving them side by side. It worked great. Everything that was on the 5s is now on the se. So i went into the settings on my se, tapped my apple id/icloud and scrolled down i noticed that both phones were on their. So i removed my old one using the se. ( i thought i would have 2 backups if i was to leave it) Now when i log into Icloud.com and click on the photos, ive lost years of photos that was saved on icloud from other previous backups and phones. it only shows whats on my old and new phone. Is their anyway i can get these back?
