In-app notifications completely stopped working for user (emails still received)

[Lucy Antonyan]

Hi everyone,

I’m facing an issue with a user in Jira where in-app notifications have completely stopped working. The user does not receive any in-app notifications (no updates, no mentions, no assignments). However the email notifications are still working correctly.

I've checked user notification settings → in-app notifications are enabled.
Tried different browsers and incognito mode.
Issue is not project-specific

What could cause in-app notifications to completely stop?
Any guidance would be appreciated.
