In Tanzu Hub UI app health is showing org and space GUID instead of the actual names. When creating a dashboard, only app guid is shown and not the name.
Tanzu Hub 10.3.5
The design is prone to confusion and errors as the user needs to know exact guids instead of using human friendly names for the apps, spaces and orgs.
R&D are aware of this issues and are working on enhancements for the UI. The enhancements are planned for next release. There is no ETA yet from when those improvements will be released.
If you come across any other limitations similar to the ones described above, please open a support ticket to report it.
