First and foremost, I use iCloud to login to my macbook pro. When I want to sign into the mail app, there are no messages. I hit the "refresh" icon and it tells me that it can't connect to iCloud due to an issue with my apple ID. I tried adding the iCloud account on the mail app, and it tells me to login. then it tells me that there was an issue with iCloud for my appleID. Is this because I have a primary email and a second (verified) email? I'm trying to add my verified email into the mail app but it just doesn't want to allow it or something.
