Memrise app keeps minimizing on loading screen if Im logged in

Im unable to use memrise to my iphone 7 because the app would pass the space ship loading. The app will keep minimizing. It doesnt crash but it I keep trying to click the app it will so I cannot even see anything other than the loading screen with the space ship.

If I uninstall the app. The app will work on the login screen but if I login. Then it repeats the issue and I will login>go to the space ship screen>black screen>Iphone home page

The app is still running if I look at all windows running but if I try to open it then I will get a black screen and back to the iphone home lage

I tried restarting my phone and uninstalling but it didnt work
