Trust Z2M map or the main tab's LQI?

based on the main tab, i have 2 zig devices offline:

BUT looking at the map, i see something else totally different:

anyway, is there a way to get a daily report of when devices go missing/unavailable?
it is really really annoying how my zig devices mysteriously vanishes at least once a week. this never ever happens with my wifi and zwave devices. im ready to tear my hair out or all the zigs out now.
