After a while HSS does not work anymore and flash settings stop being updated
I have an issue with two V6II (FUJ.A.004) and a Metz M400(fw 1.2) on Fuji: after power on, everything works for a while, but after changing settings and shooting for a while, something goes awry: the flash power settings stop being updated on the flash (they are still updated on the RX unit's display), also HSS stops working (ss >1/250s no flash visible). Switching the RX unit off and on again appears to restore correct function. Apparently something in the RX unit. A cannot pinpoint a time or a sequence of commands which leads to the faulty state.
