I got and reply in message on Reddit from a fellow with the same issue. He stated he changed either the Flashes or the Transmitter. he did not specify but replied to ask if it was the TX or the flashes. I'm putting my money on the TX because i don't understand how i get 2 NEW flashes from the box and and they both behave the same... so i would think that we Should replace the TX and hopefully thats the issue... I would love to think that it would be because there little to no information about this problem online.. so i feel almost very alone on this issue...
