Does anyone know if MF3 and MF4 are 32 bit or 64 bit? I've just read that when ios11 drops, all 32 bit apps will be rendered useless. I'm currently running MF3 on a docked iPad 4, I went back from MF4 because the sliders were lagging, possibly due to running it on an "older" iPad? If MF3 isn't going to work then it means it's time for a new iPad....
