I have a phantom 3 pro that has never been crashed and has worked flawlessy.  I made the mistake of of updating my ipad mini 3 to 11.3.1 and now I have horrible fpv lag. I would guess the lag is 20 to 30 seconds. Is any one else experiencing this issue. I am wondering if i should roll back the ios update

You can try it to see if it helps.  It worked for me.

No luck with rolling back the update. I can only reinstall 11.3.1 I did a reinstall and seems a little better.  Flying with recording off is a lot better.  When I start recording it's horrible. Wondering if I should just purchase a new tablet.
