After update server from 9209 to 9223, the notification bell doesn't work.

When a technician receive a ticket or when a requester reply to a request, the notification bell Doesn't work. ( if I click on bell inside there are notification, but near the bell there aren't number of notification like before update.

I Try to made a new server with only 9223 version, the same issue.

I hope it's clear my issue.
