i recently posted in a topic where the user pinged multiple people using @ (including me) but i have never received any notification in the events tab for it. it already happened twice on the same topic. i got notifications from other users today when they used an @ (they only pinged me) so i'm not sure if it's it's the number of users pinged that is causing this error or something else.
i'm using windows 10. google chrome.
[edit] i'm getting the ping notification now (but it's a new ping) when there are multiple users so i'm not sure what happened.
