iCloud photos won't turn on
when i go into icloud settings i move "iCloud Photos" to on and it pops up saying "Syncing photos via iTunes is not supported when iCloud Photos is turned on. 1 photo will be removed."
Then i can choose Remove Photo or Cancel. I choose "Remove Photo" and another pop-up comes on screen saying "iCloud photos could not be turned on. try again later."
I have done this several times since getting my new Pro about a month ago, any tips??
iPhone XS Max, iOS 12
