Display bug still not fixed

Go back to version 1.4. Display worked perfectly then. 1.5/1.6 introduced a display bug.

V1.4 worked now v1.5 stopped displaying

Seems the update from a week ago made this app stop displaying properly, which was the reason for the update. Great app and Bluetooth transmitter until the update.
