NeoChat is hands down the best Matrix client there is. Element still feels unpolished, clunky and confusing. I think it would be important to keep this NeoChat snap up to date.
The official KDE crew is behind this snap i reckon? Please provide this maintenance.
Ps. i think even the name is spot on: Matrix network, so Neo(chat)… 
the flatpak one is already up to date for the record https://flathub.org/apps/details/org.kde.neochat
