Can't enable icloud photos / icloud photos won't turn on
I upgraded my icloud storage because I didn't have enough storage for a backup of my iphone 7 for quite some time. The new backup was only going to be 3.5 gb because I didn't have icloud photos turned on. I upgraded to 50gb and thought oh good now I can turn on icloud photos. I get the message photos synced from itunes will be removed ...that is fine by me because they are on my macbook. When I click remove photos I get the message icloud photos could not be turned on try again later. OMG this is frustrating....is anything ever as simple as it should be with these things?
I eagerly await any responses!!
