On the app, I use to be able to heard audio on the recording clips through my iphone but now I can't (yes the volume is fully up and not hooked up to any bluetooth). I can hear audio in the live stream and I know it records the audio because on my husband's samsung android I can hear the audio on the recorded clips but just not on my iphone. I've tried to un-install and re-install the app on my phone but it didn't work. Has this happened to anyone else?
