Channel Notifications still notifying on muted channels
I have a large(ish) Team of 172 members and have at least a dozen instances of people telling me that they are getting notifications of new posts even though they have the channel notifications turned off or even have the channel itself hidden. I have verified that they have their notifications set to Off for "All new posts" and/or that they do indeed have the channel(s) hidden. They still get banner and Activity Feed notifications whenever there is a new post, even without any mentions at all.
I have provided a couple of screenshots to demonstrate. One is of the channel setting showing that the "All new posts" is Off. The other shows a notification in the Activity Feed for a post that was a reply in that channel to a post that I did not create.
We have probably around 100 Teams created and this only seems to happen in Teams that are large. I have gone so far as to create a brand new Team with a slightly different name and add the same members back in, essentially "re-creating" the Team with a brand new setup (hence the different name). That did not fix the issue either, although it affected different people after I created the new one. Some people have the issue in both Teams, some were fixed in the second one, some didn't start having the issue until the second one. This happens when using the Desktop App, the Web App, or the Mobile App so this definitely appears to be a bug on the backend rather than a client configuration.
I have performed the following steps in an attempt to troubleshoot:
1. Setting Notifications for the channel back to On, waiting about 10 minutes, changing them back to off.
2. Manually logging user out of Teams then logging back in.
3. Uninstalled/reinstalled the Teams desktop app.
4. Uninstalled Teams Desktop app, deleted the following folders manually, rebooted PC, then reinstalled Teams:
d. "C:\Users<user>\AppData\Roaming\Microsoft Teams"
Alas, nothing has worked.
I also raised a User Voice for a similar issue:
Out of curiosity, how many users do you have in the Teams that are having these issues? I've noticed that there appears to be a threshold where if you have less than a certain number, the notifications are fine. Over a certain number, and they get wonky and keep sending notifications to random users even if they have the channels muted.
Unfortunately no, I have not received any feedback on this. It continues to happen.
Have you got any feedback on this issue. We are facing the exact same issue in our organisation. It's working for some users and not for others. When I raised a support ticket, Microsoft has asked me to raise a user voice. Voting for this issue instead of raising a new one

Allow notifications to be turned off more effectively
Clicking "turn off notification" on a thread isn't working as expected.
