I purchased a Nissin i40 speed light because I read that it had high speed sync capabilities with the XPro2. After hours of frustration thinking I did something wrong, I discovered that indeed the HSS capability is indeed broken after firmware update 2.0.1. Apparently the Nissin is not the only casualty and I have to say that it appears Fuji may have intentionally broken the capability to force users to buy the more expensive x500. While I hope this is not true it appears so. I'm posting this to allow others to vent their frustrations and hopefully arrive a a resolution that doesn't involve buying more equipment.
BTW. I also have a x70 that works perfectly with the Nissin.
Thanks for you help in resolving this
