I was able to find a solution to this problem. I am using an iPhone 6s.
First, i looked at my phone (device) and confirmed blue tooth was connected to my fx100. Then I opened my AMPLIFI app, i went to the settings tab, followed by "device flash" and tapped on the most recent update (2.50.2?). From there, i tapped an update button that was within the screen (i cant remember the exact name, sorry). It turned out i needed to do an update through my mobile device, which took about an hour. i left my phone sitting on the processor for the time it took.
My FX100 now appears to be working as advertised, and I am very happy with it.
If you have any further troubles, let me know and i will try to help. The update took about an hour, but it worked. I can now use the FX100 to its full potential and it is working great.
Thank you
