I recently bought the new X-T20 next to my X-T2. With the X-T2 the Cactus V6 II works perfect, but with the X-T2 my results are not reliable. Most of the time I see part of the image black. So it's not syncing well. I have done all the steps like learn HSS and have turned Force HSS on. Sometimes it delivers, but most of the time not. Is there an update coming?
