I'm getting an error after clicking on a TestFlight Beta version invite from email. The error says The Apple Account you're currently signed in with, ****@outlook.com, doesn't match the one associated to this invitation. The invitation was sent to the email that I use to sign into my Apple account (it is my apple id) and I am signed into my iphone with that account. What can I do to get the invite to match up and go through with TestFlight?
