I am unable to get any pop-up notifications on my phone from the Teams app. I have checked the following settings: On the app:
Menu/Settings/Notifications:

Send Notifications - "Always, even if active on desktop"

Push Notifications - All selected

Sound - set on with vibrate

On the phone:

Settings/Notifications:

Teams set to notify

Advanced:

Allow Notifications selected

The activity feed does not show private chat messages but it does show private chat reactions. This is very confusing. Either the activity feed should show both private messages and private reactions or neither.

Currently, when I receive a message, a preview of this message is displayed in the notification toast. As we will be using Teams at work, it would be great for privacy if I had the option to turn off these previews, so the notification toast will just say "New Message from XY"

iOS 13 beta not getting notifications of new messages

Teams should respect Windows Focus Assist settings. I'm not even sure how apps are allowed to override Windows settings like this.
I put Windows Focus Assist into Alarms Only mode so I could record screen captures and I Teams kept popping up notifications over my application. I had to completely exit Teams so I could finish my task.

I want to reply to DMs quickly, but find that many alerts are activity alerts that don’t need immediate attention or in some cases, no attention. But I find myself flipping over to Teams a lot in case it is a DM. Can you somehow make the notifications different? Thanks!

Currently Teams is sending notifications towards other users when they are offline or unreachable. In those notifications the first word of the displayname is being used instead of the full Displayname or just the given (first) name. In large organisations this leads to very confusing funny situations. As an example we use as displayname the last name followed by a comma and then the first name.

So at the end you get notifications like Hi Van, Van has send you a message.

I want to prepare a post in a conversation now so it will appear at a later (specific) date/time.

When you send a message to your team chat, team members don't get any notification. It's so surprising that such a basic feature has been ignored constantly.

There are some apps that I would like to use with my team or I simply want to make announcements or send a group chat to my team but nobody knows what's going on unless they choose to check the team chat page.

Please bring this basic feature to Microsoft Teams as it's really frustrating to be unable to notify members of the team of the chat.

I need a public-facing information that is describing how the Suggested users are selected in Chat.

The Teams app is constantly asking me if I "like the teams app", and full-screens a call quality feedback after most calls. This is highly annoying and distracting. I always get mad at it and say no. Not because it asked, but because it continually asks over and over again like an incessant child with histrionic personality disorder.

Please make it stop!!!!

There is no sound notification for app so ppl miss messages.

When running e.g. Skype meeting and having portal.office.com open there are sound notifications for every email being received, something that can be very annoying.

It's possible for each user to turn this off, but we want to be able to turn this off in our organisation by default.

These settings are available in GUI through Office 365 Settings > Notifications > Reminder Sound & New Mail Sound.

if you are posting a new conversation in one channel, and want it to also show in the "general channel" so no one misses it as they are reviewing a day's work, you should be able to mark something in the conversation or reply to have the comment show in multiple channels.

Currently, Teams automatically changes your status during an Outlook scheduled meeting to "Busy." Can you make it an option to have it automatically change to "Do Not Disturb"? I often take my laptop to in-person meetings and keep getting distracted with banner messages.

Teams does not provide any notification when someone posts to a Team channel. We have people not realising that someone's said something in a channel because people expect to have a notification that this happens. No one constantly checks Teams to see if there has been any activity.

Could there be a banner notification at least on a "per-Team" basis telling us someone has posted something to one of our channels?

At a minimum, some kind of generic notification that activity has occurred within any one of your Teams would be useful.
