How to set old iPhone 7 to share photos with new iPad Pro
Bought a used iPad Pro 2017 and finished the initial setup manually. Then downloaded some apps so the iPad would look like the iPhone I have.
After uploading all the photos I had on my iPhone to iCloud for the first time which took roughly 20hrs, I got my iPad to check whether I can view the photos I uploaded with my iPhone. I hit the photo and there is nothing I can see.
I did some checking and I see that I have two Apple ID’s on my iPhone and I had setup a single ID for my iPad which I read one Apple ID was all I needed to access all services offered by Apple.
Is this the reason why I am not being able to see my photos on my iPad since I don’t have a separate Apple ID for iCloud like on my iPhone? If so how can I change my two ID’s on my iPhone into one single one identical to the iPad?
I am not good with computers and I don’t know how and what to do to correct my problem.
Your help will be appreciated.
