App will not start on tablet or phone


I have been using the app for a few months. It now opens the start screen and just displays a message saying ‘trying to connect to server - please check your internet connection’

The tablet (the same one I have always used) has to be restated to get out of the app at that point.

The connection is fine on all other apps

I have deleted and re-downloaded - using the same internet connection and still no joy.

Any ideas what I am ding wrong?
