Downloaded directly from app, When played on my phone, no audio. Copied to my computer the d/l file, with no audio until I tried VLC. I also tried sharing from the Wyze app to the family who were not able to hear it, either.
There is no recording on the memory card - seems the advanced, local Storage, setting for Record Events Only did not record to the card. I have changed to Continuous recording and will check it later.
