A small Warning on YN EX3 RT and Canon 430EX III RT

Just got a new canon 430 EX III RT. I was surprised to find a wireless master mode with some strange grouping settings (cannot find a Ratio options as in the 600 EXs).

Unfortunately I am writing this post to announce the world that as far as I see the unit is not compatible with the Yongnuo YN EX3 RT  transmitter. The unit can connect correctly to the other 600 EX RT but not the the new canon gem. 

For your reference if in the future the device is going to be updated the firmware will be found here:

EDIT - the firmware 1.9 makes the trasmitter compatible with the flash.
