I’m having problems with my IPad locking up when using FltPlan.go app…it might work on one leg correctly, then after landing and taking off on next leg, it locks up,or it might work for a while and then freeze up…the only way to fix it is to turn off iPad and restart…only problem is that in the air there is no internet so it won’t work..any ideas? P.s. I’m a mental midget with computer technology..
