Hello, Just to let you know that I've had reproducing this in my lab tenant , if you need any further traces or screen shot,

[Vaibhav-MSFT]

@lazar29092015 , If you can provide us with some steps to repro that would be helpful

[lazar29092015]

• create a new app through Teams dev Portal,
• fill all information needed,
• choose an icone which respect the requirement, in term of size mainly,
• and publish the app + approve publishing in TAC -> manage apps,
• you will see the application whithout icon shown , whether in end user side via Teams or in TAC -> manage app

that's it, attached a pkg I test from my side, but this is something happen and raised for two of my customers ! A_LEX - Le Bot Juridique (1).zip

+1 #push Custom App created through VS Code with the Teams kit and also through dev Portal both Applications only show the icon for me as an owner of the application. Could it be that firewall blocks the pngs?

[lazar29092015]

I'm not sure this is related to firewall restriction, I had a similar case with my customer and the solution has been fixed after lowering the size of the PNG icon, from my side I lowered the size icon from 150k to 30k. there is a known limitation of this described here https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/design/design-teams-app-icon-store-appbar

if the owner is able to show the icon , I suspect that just the url page use the cache to show this value , may be a owner test elsewhere could confirm this
