Sucker for punishment?

I've spent several days during the last year trying to get Fujifilm cameras to work either with a cable tether or with their camera app, so far with very little success. So to mark the end of the year I thought I would try again with the app on the X-T2 and X-H1 - I didn't even waste time trying to get the tethering to the PC to work, and I might as well have saved my time with the app as well!
