I have several V2 and one new V3 camera all with SD cards. The V2s can record during playback, but the the V3 cannot. It looks like it does, but the recording is blank in the album. This only happens on my Google Pixel 3a XL Android v11 phone; works find on iOS phone.
Rebooting the phone and restarting the camera didn’t fix it.
Anybody else see this? Is it a Known Issue? Any suggestions?
