I have been having trouble lately synchroning my flight data from one ipad to another. I've tried the synchronizing process a few times, but still cannot collect all the data. Tried logging in/out, then synchronize with no affect. They are both ipad 5's. I've got about 20 hours, but when transferred.. 9. I know keeping physical records will be the next step. I would love to see the hours on my pad though. Please help if you have any ideas.  

I’ve only had issues if my two iPads have different accounts.   I fly two birds but use both iPads for testing.   One account is personal, the other is work related.   Two different accounts.   Make sure you’re logged in properly to the same account on both when you sync.
