Hi @VitaliiUshanov ,
For the problem about the icon not being sized correctly, this seems like a bug so could you raise a support case here please. The support team should be able to help you get to the bottom of the problem.
For the second problem, this is the same as that reported in The vendor name is not displayed on the agent when listing the app via Browse Agents. I raised this with the Rovo team and created ROVO-554 (internal to Atlassian), but the team have not provided an estimate of when this will be addressed. I’ll ask the team again.
Regards,
Dugald
