Q:

Microsoft Teams azure botframework ICON

I'm looking way to change icons of my bot (botframework botbuilder c# azure web app) using manifest.json (https://docs.microsoft.com/en-us/microsoftteams/platform/resources/schema/manifest-schema) they work like a charme for green icon and doesn't work for the 2 red circle ? :' : 

I didn't know if it's a problem due to the picture but i have following the site
 and preconization : https://docs.microsoft.com/en-us/microsoftteams/platform/resources/schema/manifest-schema
Note : All icon work if i'm deploy the bot using channel link registration on Azure portal. 
Sincerely,
Pascal.

A:

Solution : 
In my case it's not a problem due too icon image present on manifest zip. 
But it's a problem due the icon present on setting of ("bot channel registration") in Azure portal. 
After change you icon in the setting "bot channel registration" you have to disconnected and reconnected from teams and after a small time (1 or 2 minutes) the icons work in teams.
