When mounting the flash/trigger on the camera, the Fuji camera will show TTL mode forcibly and will not show Manual mode, but this difference in camera display has no effect on our flash/trigger functionality. I.e., when the trigger is set to M mode, the flash follows M mode and the adjustment function can be used normally.

Don't worry, V350C's functionalities are not affected by this design difference.

The "M" icon on the Transmitter unit does not matter whether it is displayed or not, since V350C can control three Receiver units A/B/C groups regardless. 

When the V350C is a Transmitter unit, it defaults following the Receiver unit's power output in A group to sync flash.

If you don't want the Transmitter unit power output the same as the Receiver  unit in A group, here are two ways:

You can turn off the V350C flashing or use the A group for the Transmitter unit only, with no control of any Receiver unit via the A group.

Different model has different internal function designs, so they won't work in that way.

On TT685II, press the Lock Button for 2 seconds to unlock.

Canon R series mirrorless camera doesn't support the external AF, and it only allows to use of its internal AF.

Unlike some older DSLR cameras, Canon mirrorless cameras generally do not have a dedicated port to connect an external autofocus system/module. This is related to the mirrorless camera principle, for which we currently have no solution.

BTW, correct AF in the flash or trigger, but you find that the camera does not activate the autofocus assist beam, this is because the camera has a correct autofocus already. That's normal, this is how it works.

The shutter speed may be too high for the flash.  Lux Junior does not support high-speed flashes, which can be out of sync. A slower shutter speed is recommended.

Yes, that could be enough power.

Make sure that in the menu section for both lights that you have ‘standby’ and ‘sleep’ set to ‘OFF’. 

To turn wireless mode off press and hold the sync button until the wireless symbol flashes, rotate the dial until the CH number disappears leaving only the wireless symbol flashing, then press set.

Yes, this adapter will allow you to connect the magnetic dome diffuser to your V860II. The Godox AK-R1 kit has extra options that work great too.

Allows you to fire older models of lights since some cameras don’t have a sync cord.

The main benefit of the V1 is not just the round head itself but all the accessories that the round head is compatible with. The AK-R1 kit includes a grid, snoot, gel holder, color corrections gels, dome, and bounce card. They all attach easily to the V1. 

Yes. The XPro-C had a firmware update (v1.8) to make it compatible with the T7 and T100.

The Godox AD-S60S, AD-S65S, and AD-S85S. Those connect directly to the AD400 and are very portable.
