Hi, today I have been trying use mattermost on computer’s in my company, I installed it on 3 different pc with windows 11 and I didn’t have windows notification on any of those, neither sound nor popup. I searched through the internet and trying some solutions from there but without results (like with turning notifications on etc, everything what is simple to do). Red little dot beside icon on windows bat shows without problems, but there’s no sound and push notifications. Do you know why? I add that I don’t have mattermost on notification list in windows (settings → system → notifications), I tried inslall few version 5.6.0, 5.8.1, 5.9.0 and nothing
