On the instance lists of the VRChat Android application, it is not possible to see which group is the owner of each instance.

Same can be seen with private (Friend and Friend+) instances, but this is usually not as big an issue.

This issue also exists on the VRChat website, see: website-cant-see-owner-of-group-instances
