I've been using a floodlight cam wired pro for about a year, the WiFi strength wasn't great so I added a chimney pro, now both devices report as good signal strength. About a week ago I realised I hadn't had any notifications for 2 or 3 days, I checked the app and nothing had recorded for those days, I couldn't connect to live view either so ended up re-adding the chime and cam to our other network . It worked after this for about a week, again yesterday I realised it has stopped recording for a few days again, live view seemed not to be working but suddenly started again , so seems to have fixed itself. I don't know what's up with it.
