iPhone photos stored in iCloud
Message "Photos and videos synced from Finder will be removed. Syncing photos and videos via Finder is not supported when iCloud Photos is turned on." I haven't got a Mac, I have an iPad, there were some photos of my old iPhone in there. Does this message means my photos stored in my iPhone Library which were also in my iPad will be removed from my iPhone if I turn on iCloud Photos now?
Please help.
iPhone 8 Plus, iOS 12
