Notifications found on phone (some of which are GMail, Groupme and a few others which are enabled in KDEConnct to sync notifications to pc) do not sync to pc. KDEConnct-1.2.1-r2 - desktop KDEConnct-1.8.2 - android plasma-desktop-5.12.4 Android 7.0 Phone: Ulefone Armor 2 kdeconnect seems useful but currently doesn't seem as useful as it can be.
I will add that vice versa, pc to phone notifications do NOT work either.
There's a bug in KDE Connect 1.2.1 regarding notifications, so this might be solved with KDE Connect 1.3 (released last sunday). Could you try that? PC to phone notifications require you to enable a plugin on both android and the desktop, did you do that?
Notifications to and from pc works wonderfully with 1.3
Fixed in 1.3
