Navigraph iOS bug cannot login

I am having an issue with Navigraph charts on my iPad. When I login it asks for my email and password, I enter that and then it says fetching air cycle, maps etc. Then the login screen just comes back on. Please see attached a screen recording of what happens: Navigraph bug - YouTube

I have restarted my iPad and also reinstalled the app and still no luck. I attempted using another WiFi network too.

Hello, you may want to log out of Navigraph and try restarting (full reboot of the ipad) then try again.
