The OUTLINE icon displayed earlier is not showing now after updating the teams app.

The configuration in .env file:

CONFIG__MANIFEST__ICONS__OUTLINE=resources/BotLogoSmall.png

The configuration in Manifest file :

        "color": "${{CONFIG__MANIFEST__ICONS__COLOR}}",
        "outline": "${{CONFIG__MANIFEST__ICONS__OUTLINE}}"
    },```


The image BotLogoSmall.png is in the resource folder. This image has been displayed properly for more than a year. Now, suddenly, without any change in the bot source code or recent publishing of the bot in the Partner Center, the image is not displayed



 We tried the following things:

(1) We cleared all the team's cache

(2) Go to your bot in Azure>> to settings on the left-hand side - you will see the first option to upload a custom bot icon. This will update your icon.

But still, the OUTLINE icon is not displayed. I have marked it in the attached image.
