Go to tools --> Notifications --> Click "delete this page of notifications" Delete them all. Then restart browser and lets try again.

if nothing works, try joining the irc chat,,
afaik you get notifications there too (but i think it stays within the browser tab and doesn't "jump" outside).
just try it i guess.. https://forums.d2jsp.org/chat.php

deleted and restarted

tried already, l cant remember to keep it up. l need my notifications at all times

Test.

If this didnt work, lemme know.

do you know how to receive notifications in a reliable way?

Could it be that there's a flood control for notifications? I noticed you trade A LOT so you're probably getting bombarded with notifications, I'll go on ahead and ask for you.

didnt work, same thing happen, l get notifications in the center but no popup/sounds

I believe sounds don't work for notifications on JSP.

You can go to 'View Site Information' in your Address bar and choose to block or allow notifications. Lemme know when done.

yes when working properly l get a popup on bottom right with the sound of my choice in notification options

blocked removed restarted allowed back and turned back on
