V6 II hangs EOS M3
I am facing some issues with the EOS M3
1) The V6 II will disappear on camera after a while (flash icon missing)
2) The V6 II hangs the EOS M3 Ext Flash menu when TTL pass thru is enabled (it force shut down the camera)
3) Sometimes I can enable the TTL pass thru, it goes into an error.
