Photos from icloud do not show in iPhone photo app
I recently bought a new iPhone, but I cannot see all my old photos that are in my iCloud account in the Photos app of the new iPhone. I switched on 'iCloud Photos' on my iPhone and since then, all pics that I'm taking with the new iPhone are uploaded to iCloud (and I can see them in my other Apple devices), but I still cannot see my old pics from the Photo app in the iPhone. Noteworthily, I see one old shared album in the Photo app, but not all the other pics that I did not put in a shared album. Is this a known issue? Thanks for your support!
