"Our severs cannot be reached..."

I am trying to log into my account and I keep getting the following message:
“Uh oh! Our servers cannot be reached, we’re looking into it. Please try again later.”

I am on Iphone with updated app and phone. I have tried on Cellular and Wifi every other day over the past 2 weeks. Can you advice how to log into my account?

I have tried again today and it now proceeds as expected. Thank you for fixing!

Now my copy of the app is not logging me in that way. Why did it log me out.
