Our Teams App's Messaging Extension Icon Is Blank On New Teams

[johnzhang06]

Our custom Teams App works fine on old Teams, however, after customers switch to new teams, our app's icon(outline) is displayed as blank when:

1. Our app (messaging extension) is pinned, AND
2. The chat is opened from App Bar (side bar), instead of from chat history

(See the screenshots for comparison)

The icon is displayed normally in the Classic Teams client.

Here's the icon file:

Please help investigate. Much appreciated!

@johnzhang06 - We have tested this in classic and new teams in windows in web , it is working fine classic : new teams :

@SaiPratap-MSFT Can you please try pinning the app to the messaging extension (with the provided icon) and see if it works? Thanks!

[SaiPratap-MSFT]

@johnzhang06 - If you clearly see my screenshots, Here the app is pinned. If you are asking to try with different icon, please provide that icon .

@SaiPratap-MSFT Hi, the icon has been attached but it's not easy to see.

@SaiPratap-MSFT Hi, the icon has been attached but it's not easy to see.

Hello @johnmiroki - Could you please share your icons color and outline, so that we can test it from our end? FYI... We have already tried with other icons which are working fine.

[johnzhang06]

@SaiPratap-MSFT Thank you for following up. The icon should be transparent with white outline. It works well with Classic Teams.

Hi @johnzhang06 - We are not able to download the app icon and its showing below error.

Could you please share your manifest zip file containing both color and outline icon, so that we can test that from our end?

@johnzhang06 , @saumyanayak10 - We tried to repro this issue using the icons provided and its rendering as below in our case. Classic Teams:

New Teams: We have noticed that, if the application is pinned the icon is showing blank and if the application is not pinned its showing properly. App is pinned:

App is not pinned:

We have raised a bug for the same. We will inform you once we get any further update from engineering team. Thanks!

Hi Microsoft Team, @Prasad-MSFT Thanks for acknowledging the issue. Could you please help me understand why this thread shows "closed" at the top left side of the screen? If it is mistakenly marked as closed, please could you change it to "in progress" as we are still awaiting a fix? Thank you.
