Hello, I have updated latest firmware for my Osmo Action 4 and DJI Mic 2. Then, they have stopped auto-reconnecting if I turn off and turn on one of them. I must connect the Mic 2 manually and very annoying. Is there any way, I can rollback to previous firmware. Thanks in advance.
Osmo Action 4 Firmware: 01.04.07.10
Mic 2 Firmware: 04.04.05.13

You may need to do a factory reset on the mic, then re-link. I have had no issues with mine, btw. Same firmware versions.

I have removed the battery then put it back after 10s then the problem was solved. The root cause maybe I have connected DJI Mimo app and DJI Mic 2 at the same time.

Hi there,
thank you for reaching out.

I would like to reopen this problem.  I recently did the Firmware Updates for the DJI Mic2 and the Osmo Action 4.  Now the Action 4 will drop the Mic2.  I have had to reconnect frequently today.  I tried a Factory Reset on the Action 4.  It let me reconnect the Mic2.  But later while I was recording it just dropped the Mic2.  Lucky I had Record set to on for the Mic2 and the audio was there.  I have tested this with both my Mic2's.  It is not the Mics unless that firmware is the problem.  I feel there is something going on with the Action 4.  I can't be the only one having a problem.
