App version ( 1.0.56 ) vision app, was the version with a bug in the extender update, DO NOT USE THIS VERSION!
I have not tested newest versions ( 1.0.58, or 1.0.60 ) but will in the FUTURE!
Next
If you have not flown in a while ( P2v and or P2v+ users only ), you start it up and get this warning ( you must upgrade extender ) DO NOT UPGRADE, repeat DO NOT UPGRADE.
Instead
Shut everything down!
1) delete app from your phone, either use newest app, or revert back ( p2v+ users DO NOT GO PAST 1.0.48 ) as p2v+ was added at this upgrade and is not avail on earlier versions of the app. P2v NON plus users can go all the way back to 1.0.19 first version of app.
Now with new app installed,
Go fly and have fun.
IF YOU UPGRADED EXTENDER, and have NO FPV, due to it:
P2v+ ( mainboard in gimbal is toast )
P2v ( 3rd board is fried )
Either WILL require, replace or repair!
A few of you will experience lost FPV, but simply reverting or upgrading app will cure your problem!
Next if your extender went completely dead ( won't turn on ) , I've found it will loose internal memory, and require you to rebind to fix problem.
Here are a couple videos that will help:
1st finding your unique MAC ADDRESS, to your camera ( p2v ) or your wifi module ( p2v+ )
Easy mac:
Ok those who want to revert app ( iOS users only )

Take Care, Fly Safe!
I use ( 1.0.48 ) first version to add vision plus. But feel free to experiment.
I wanted to also add fixing the app will not fix FPV if you upgraded the extender through the app.
( most likely gimbal mainboard ( plus models ), or board 3 is fried ( vision non plus models ). Will require repair or replace. The mods are working on a sticky on not to upgrade extender, as not to brick your FPV, in old app version 1.0.56, this version had a serious bug, causing all this CRAP!
Good luck to you ALL!
