I do not have a Navigraph account, and I am also suffering the disturbing red Navigraph error messages in the EFB.
That happens even though I have chosen NavDataPro as a data source in the configurator (a setting that is remembered on the tab "general"each restart).
But in the tab "EFB settings" the configurator always jumps onto Navigraph after each restart - I can not change it.
Is there a way to see anything else than the error messages on the "EFB"? If not, I would prefer to put it off.
