By default, discord notifications used to be automatically enabled for every user. However, since the last few updates, me or any other forum user hasn't been receiving alerts/notifications on discord. After checking the preferences section under the forum profile, I've found out that all discord alerts have been disabled/unchecked. Moreover, if you try to enable/check all of the discord alerts and save, everything gets unchecked automatically on clicking save. But, if you enable/check all discord alerts except one (this could be any alert) then it works as usual and saves successfully. If I try to check the last alert after saving then everything gets unchecked again. Seems like everything reverts back to being "unchecked" if we try to enable all of the alerts at once.
