Since the D210 doorbell firmware updated from 1.0.13 to 1.0.15 the connectivity has been worse. Takes longer to get the live feed, trying to view SD card recordings sometimes just doesn't work. I have to force close the app and reopen, then maybe it works. The phone call system is also not great when someone rings the doorbell. Sometimes I get no call coming through, when I have received calls the audio quality has been terrible so I haven't been able to have a conversation with anyone.

All of these things seemed more reliable on older firmware. I've tested this on a network where my phone has good connectivity/signal and the doorbell is well with range of decent WiFi signal. Please can someone look into this?
