DTTG 2.3 Black Screen

After a recent update to both DTTG 2.3 all I get is a black screen on both my iPhone and iPad. I’ve tried restarting both devices as well as upgrading to iOS11.0.3 with no luck. Is there any other solution than to delete the app and sync the data again?

That would be the quickest way to handle it. And in some cases, the only way.
