Hello Tony,
Ok, the site is not mine, but he does have most of what you need!
Ok
Lately people who have pulled out their drones after some time, their apps have auto updated, so when they are turning on their stuff and open app ( DJI vision app ) it says, you need to update your extender, and has a check for yes, IF YOU DO THIS, it will burnout your camera! There is an issue with that update, and DJI won't correct it as p2's are discontinued, so they do not care!
Anyhow,
If your phantom flew find the last time you flew it, I would NOT UPGRADE! IF: your app has auto updated, to the very newest version ( version with bad update ) you will want to REVERT your app to an earlier version ( one WITHOUT the bad update ) 1 back is fine or go back farther ( up to you ).
Here is the how to:
Here are the codes:
Ok
Now I've compiled the numbers and placed them with APP versions and dates for you: ( you can search the app in iTunes, and search versions, and what each version has or has added ) too much typing for me, but this will help:
