New Copilot Studio experience - MS365 Copilot and Teams - Channel About Info

We have imported a managed Solution into our Production Environment and all Objects successfully migrated, with the exception of the Channel 'About Info'. We find we can now update these About Info details, but they do not carry through into the App Manifest Download or the Submit to Org Catalogue. Unlike the Classic experience, there is also nowhere to update the Icon in the Channel Details, so only the default icon comes through in the Manifest and Org Catalogue workflow. HELP!
