I've had a couple of minor freezes in both my X-T2 bodies using both SanDisk UHS-I Extreme Pro 95mb/s cards and Lexar UHS-II 2000x cards (at different times). My cameras are both gripped and I use the Fuji branded batteries - "S" varieties. I notice the freezes when I'm shooting in low burst mode and switch viewfinder modes quickly from EVF only to LCD, then back to EVF.
I also notice the cameras have difficulty waking up from sleep mode. Several half and full presses of the shutter don't wake the camera up, even after 3-4 seconds per press. I pull the battery tray from the grip and then it wakes up when I turn back on.
