TeamSpeak TeamSpeak notification issue

Affected version


Some users are not receiving thread notification alerts on TeamSpeak even though they have watched the whole sub-forum. They receive the alert on TeamSpeak about 1 out of 50 times, despite the fact that we tested this issue by posting a thread in the same sub-forum, it still doesn't always (as mentioned before, alert is received only about 1 out of 50 times) send an alert. It is working fine for me and a few others. However, almost 50 percent of my TeamSpeak staff is not receiving alerts on TeamSpeak. I've also properly double checked their notifications settings by comparing them with my own forum account. They are all receiving notifications on forums but not on TeamSpeak.
