Refresh problem, notification problem, devices status problem – Who Uses My WiFi? (WUMW) Protect your network from intruders Review

Main problem is this app would not refresh on its own and sent notification about devices even when the app is closed. Then when you manually try to refresh, it won't refresh at all sometimes after many tries or will refresh after few tries. Very annoying. Recently, although I have almost 6-7 devices, it shows only 2 active devices. Few days ago it showed 8-10 devices. Couple of MAC add and ip add looked weird but remained inactive for most part. Some active devices never showed up. So really not useful.
