I am relatively new but have found an issue in logging in. When I first set up my ios app I used xxx@AAA.tech. I was able to sign in on the web and on my mac with this format, but was not able to on my ios. After quite some time is changed my email to a dot com [xxx@AAA.com] and all issues disappeared.
I now need to switch back to the dot tech and when I did the same issues happened. I imagine that the ios app checks for valid email and a non .com doesnt work. How do I get around this?
