Fuji has famously terrible app support, its a nightmare to set up and cuts out constantly, transferring images over wifi is slow and unreliable to the point of it being useless, the remote shutter is unreliable and doesnt have any of the extremely simple to program features that intervalometer's have. You can't shoot tethered unless you have one of the above very expensive cameras.
The whole software ecosystem around cameras is awful, I would love to see some open source community initiatives to be able to control these cameras and extend their functionality but I haven't seen much of that in the photography community.
