I have mapping zoom setup on my right slider - works great. I have the messages screen, main screen and mapping screen setup on my left slider - works great.
Loaded the Yaapu 1.8.1 stable (not pre-release) of the telemetry script and the script is working perfectly. I loaded up Arduplane latest on a Matek F405 Wing & FrSky RX6R with telemetry inverter cable. Searched high and low on rcgroups and but can't find out / figure out how to scroll (if it's possible) message history on a Radiomaster TX16S.
