On the devices page of the wiki, the PinePhone pro is in the "testing" list, which has this description:
"All other device ports, including new ones. Maintainers can create merge requests to move devices to community if requirements are met on the Device categorization page. A more detailed view with a full status matrix of these devices can be found on the All devices page"
The normal PinePhone is one of the main devices, so it seems that that one has way better support.
