Please dont hate on me for pointing out the following. If you do firmware upgrades when your drone is flying well you MAY LOSE FUNCTIONS, or worse cripple your drone. Dji have a habit of pulling stuff. Also I am on app 3.1.3 and the feature is still there using older firmware 01.03.0400 and remote 01.03.0500. I can happily confirm you can change the expo for sport normal and "gentle" - which is tripod mode. I just dialled in the settings this morning and can confirm they work. So if you can use
DJI app 3 not "go4" then you will find these features still exist. However DJI wil moan at you every time you start the APP that you should now be "using 4". You can ignore those warnings as they are "cough cough".
Heres how I do things... Change the settings I need then use Lichi. You need the DJI app only for setting changes - then to fly use Litchi... the only thing youll miss in Litchi is there is no Tripod mode yet... However I think the above will sort you out... Settings via APP V3 android and then Litchi to fly with or the old V3 App... from DJI to fly with if you prefer. Hope this helps.
My experience of firmware upgrades is that i lost features and had to roll them back because aircraft became unflyable in some cases. My friend had had his
p2 grounded because of the major firmware scandal that is currently seeing a class action lawsuit against DJI right now in the US> DJI refuse to rollback firmware that bricked peoples drones. So if you are happy dont do those firmwares unless you HAVE TO.
