Windows client doesn't show notificaion pop-ups and no sounds

Our team moved from slack to keybase. No one gets notification sounds some people gets pop-ups and android client also doesn't make any sound.

All settings are on per channel settings too but no pop-up no sound.

The report concerns missing notification pop-ups and sounds in the Windows and Android clients; no files, tests, or entry points are named. Start by reproducing the problem with channel and client notification settings enabled, then verify that both clients show pop-ups and play sounds for new messages.
