App opens for a second but closes right down.  Still shows as running in the background but snaps shut.  Can't even set it up.  Tried deleting and reinstalling several times.  Same thing.

Me 2... I think it’s our beta app for ios14.2 because it worked great before that update

Yes, it seems the issue of the IOS beta

Hello there Osmo11promax. I am sorry for the trouble this has caused and thank you for reaching out. As of the moment we are working hard to adapt the new operating system to the DJI Osmo Mobile 4. If you are completely unable to use the said DJI product, kindly please use a mobile device with a slightly lower version operating system. Again, I am sorry for the trouble and thank you for your understanding.

Thanks for this!  Is there a DJI update expected anytime soon?

I restored back to 14.0 and works again... I needed it .. happy I was able to downgrade and not lose and data

How did you do that?  iTunes bu or iCloud bu?

Definitely a conflict with ios14.2 beta. I’ve confirmed with three different phone running ios14.2 beta. ios14 works fine though. Hopefully either the upcoming new ios14.2 beta will fix it or DJI will release an update to GO4. Until then I can’t fly my Mavic Pro or Air. Only phone running ios14 won’t work with my controllers...

I've already discussed this. Probable cause is listed in the known issues of the beta. Will require a recompile of the Mimo app.

Has something to do with data.
If I turn off my WiFi and cellular data, I can use the app.  

Downgraded back to 14.0.  Came back and did 2 firmware updates.  Is it working with 14.0.1?  Holding off on that until I’m sure it works.  THX!!!!!

You didn't have to downgrade. DJI Mimo has an update in the app store and now works with IOS14.2

I think at the time, he may of had to if he wanted to use the app, he may not of had a choice. (at that time anyway)
