I have had this problem all day today. Am at a scenic location and practiced MPCC prior to being at location to get the hang of it. Never had this problem during practice but started today and same thing where won't execute the cable and won't let me out. I can still manually fly and land the drone safely but then have to reboot everything to restore smart shots. Annoying as heck. Wasted all three of my batteries today troubleshooting. Also updated to the latest -01 update just released to no avail. Still presented problem. I was able to successfully set up and execute a three-point cable before running out of time today but no explanation why problem happened earlier. I am using Mot Droid Turbo2 brand new. Again annoying. Am writing 3dr tech support hoping for a fix.
Please let me know if anyone else figure this one out.

Edit - P.S. - if it helps isolate, my "freeze-up" always seemed to occur when I tried to hit "B" button to end the cable. (i.e. every "A" button tab produces the appropriate check mark response but "B" button produced no response and then you are unable to exit the cable.
