We have deployed an Azure Bot Service and activated the Teams Channel, then package the APP as usual with related manifest and icons.
The icons have also been set from the Azure Portal in the Bot Profile section (240x240px) and in the Branding & properties section (215x215px).
The app has also been deployed across the Teams users and is available as expected, but the logo attached randomly disappear.
Using the Teams web interface and the HTML inspector, we have noticed some HTTP errors related to CORS policy violation (see attachments) and we are supposing this is related to the icon issue.
Could you help us?

According to your description, your question is more related to app development, so I will also add Teams development tag to your thread. Thanks for your understanding!
