External mic
Since updating to iOS 14.4, the external microphone will not work. I have tried rebooting the phone (2020 SE). I have plugging in the mic after I start whichever app. Nothing works. I use an Apple brand camera adapter.
A little more info... when I plug the yeti mic into my phone and go to my iOS native camera app to take a video, it starts taking bursts of photos or short videos, rendering the mic useless.
When not in the camera app, the phone still vibrates every second, as if something on the phone is stopping or resetting or something. Again, we have tested the cables, devices, etc. and our conclusion at this point is the problem is due to the upgrade to iOS 14.4
