Got on! Here's what happened to me:

I tried again but with the same denial and re-direct back to the log-in page. But I did figure out what was wrong and here's what my log-in problem turned out to be.

Apparently username is not case sensitive, but password is.

My phone's browser starts every line with a capital letter. But my password is all lower case. That was the problem.

On the browser's toggle options it only gives you a choice of letters, symbols, numbers but no case selection. It just defaults to the phone's default, I guess, and automatically capitalizes the first letter of each line.

So I just typed in a second/duplicate "first" letter to my password string (that second one naturally came out lower case) and then deleted the first capitalized one so that the password was all lower-case. Then I hit "Login."

And that worked! Don't know if you can add the words "case sensitive" at the password box or not, but that might be a good idea?

Looks pretty slick! Thanks!
