any reason to change this to MEDIUM? just curious

[MarcosSpessatto]

This comes from the discussion feature. I changed that because I need that to run before the discussion callback, otherwise, we would end up without the correct number of messages within that room.

Rocket.Chat/apps/meteor/app/lib/server/lib/notifyUsersOnMessage.js

Line 187 in 28419b8

await Rooms.incMsgCountAndSetLastMessageById(message.rid, 1, message.ts, settings.get('Store_Last_Message') && message);
