Unable to sign in to the gospel living app

I am unable to sign in to the gospel living app. I can sign in to “Tools” and the church website with no problems, but when I attempt to log in to the gospel living app I get a “sign in failed for an unknown reason. Please try again”. This has been going on for several days. My Wi-Fi signal is strong. I have deleted and then reinstalled the app. Nothing seems to help. Does anyone have any suggestions?
Thank you!

Try signing out of tools then back in again.
