Having trouble getting the Flashpoint (Godox)'s 2.4GHz wireless E-TTL to work with my Canon 80D.

I recently purchased a bunch of Flashpoint (Godox rebranded) flashes from Adorama when they were on sale. Here is a list of all the items I bought:Flashpoint R2 TTL Transmitter for Canon (Godox X1T-C, firmware v18)Flashpoint Zoom Li-on R2 TTL for Canon x 2 (Godox V860IIC, firmware v1.3)Flashpoint XPLOR 600 TTL HSS (Godox AD600B, firmware v2.2, tried v2.3 as well)I was testing the new 2.4GHz wireless TTL functionality with Canon 80D. So far, all I've been getting are overexposed images. I've tried a bunch of setups to trigger the Zoom flashes as well as the XPLOR 600 w/ ETTL:on-camera R2 transmitter (overexposed)on-camera Zoom flash as a wireless master (tried both ETTL mode and Group mode w/ ETTL, both overexposed)single on-camera Zoom flash (works)On camera Zoom flash using optical ETTL (works)Wireless manual w/ R2 (works)Wireless manual w/ Zoom as master (works)At first I thought the problem was with the R2 transmitter or one of the flashes, but it seems odd that none of the wireless ETTL combinations worked. Has anyone using the Godox / Flashpoint ETTL system with Canon cameras run into this problem before? Am I missing something? via /r/photography http://ift.tt/2gUYkWI
