Good catch, I didn't see that. All of the chatter from RC Groups said it wasn't compatible, supporting only Mavic and P4P. And I believe the release notes said that too.
32 Channel Hack still works on DJI GO 4 on iOS with the P4! Just install the same file into the DJI GO 4 app folder just like we have into the DJI GO app folder. . Whether it will work on the P4P+ Android integrated CrystalSky screen/tablet is still unknown. The only trick would be installing it. DJI GO 4 does support it.So it appears that 2X zoom is still supported for the P4 with GO4, however I'm not sure about 32Ch hack, I haven't tried that yet. The GO4 interface has been dolled up a little, but maybe not since I'm use to using GO ver. 2.8.3. I see something in the menu that says "Coach Mode", I'm unaware what that is. Does anyone know? Is that a new name for Beginner Mode?
