According to iOS Battery report, Teams is responsible for 24% of my battery usage. I am not actively running or using the program, so I assume this is related to background tasks / notifications.

Ability to localise dates - In at least AU and UK we use DD/MM - its becomes confusing quickly when half the dates are in local and the other half are in US format

Allow me to use my language, 24 h clock and similar
Plus it could proof read my chats accordingly

Participants should have the capability to zoom in on the user who's sharing their screen with the participants.
this functionality is available on Skype for business, it's called Actual Size / Windows Fit

Microsoft Team currently doesn't run on Surface Hub :-(
when I clicked Join Online it's asking me to download the app however the app is not compatible with Surface Hub.

When trying to create a team, an Owner of a 365 Group can be prompted to add Teams to that Group, but only once. After adding the first group they own, they are not prompted again. There is also no way to manually provision this service to existing Groups in the Admin center.

When I am typing a message, whether in chat or channel, the conversation window scrolls up for as long as I'm typing for. A message this long will scroll up a few dozen lines, while a much longer message will scroll to the beginning of the conversation.

We create our Teams as private by default since they are about the clients we work with. We are okay with everyone at the company knowing that these Teams exist, but we don't want them to be able to join them without permission.

The problem we're having is that people keeping asking 'does a Team exist for client X?' and there is no easy way to answer that question.

We'd like a way to search for private teams so that folks can request to join them.

Rather than having to run the To-Do app separately make it a tab in Teams as most to-do items relate to work in Teams

Currently bots & tabs have one control - on or off. Many organizations must turn this option of due to data protection issues. Corporate data will be sent out of the Office 365 environment to unknown sources (bots and tabs).

What I would like to see is a granular control that allows you to enable bots & tabs for Teams that have specific Office 365 Groups classifications. For instance you might enable bots & tabs for "Public" or "Unrestricted" Teams but not for "internal" or "restricted" ones.

need to be able to drag and drop in meaningful order.

It seems that recently Teams starting converting space characters to non breaking space characters. The text with non breaking spaces doesn't work the same, e.g. a search query that not fails.

Cloud Storage like Box within Teams, keeps repeatedly prompting for credentials every 30 mins to 1 hour. Please renew the token silently before it expires. This will ease Users to access their files in Box.

The desktop app of teams logs me out constantly. I get new message notifications on my phone, but then I have to log in manually to the desktop app almost on a daily basis and the app doesn't remember the credentials either.

Hi,
we've tested a tab PowerBI with both iPhones and Android (Samsung). With iPhone the report is opened correctly with the app installed, while this doesn't happen on Android.
Since in our organization we have mixed devices, we should be able to provide a common UX.
Best regards

Better organization (alphabetize?) of apps in the plus (+) app tab. A clear summary/explanation of what the app does and if it requires purchasing.

Allow users to send praise to themselves. Sometimes you just need to pat yourself on the back.
