Invalid password on iOS 9 (iPhone 6)

I installed checkpoints today on my iPhone 6 to see how my farm phones were doing. Anytime I try to log in, immediately "invalid password" pops up in yellow. I even went as far as to reset my password, still no luck.

So, my questions are:

1. Am I the only one?
2. Does the iOS version not like special characters in passwords?

Once I get home from work I'll see if my android farm phones are showing the same symptoms. Last night I installed the newest version on them and I was able to log in no problem.

Thanks!
