I installed this latest Litchi version from the Amazon store to the RC Pro. Installation goes flawlessly. However I noticed the FLY app and the LITCHI app competing for aircraft control and neither is giving up or taking over. Every time the RC Pro starts up, the FLY app is automatically started which will prevent the Litchi app to work correctly when it starts unless when switching between those apps one executes FORCE STOP on the other. That solves the problem for either of them. Pretty awkward but I guess it is workable.
