Anthonymelwhrhs thank you for your feedback!
Microsoft Teams and Visual Studio are both excluded because they have arm64 installers, which unfortunately this current system can't handle appropriately and as such all apps with them are excluded at the moment during the preview. I understand the frustration here, this is something we are looking into how to allow these Win32 applications to be managed.
Microsoft Store (new) apps of Win32 installer type should be automatically updated through Intune to the latest version available in the store. Are you seeing that the OBS application installed on the device is not updated to the latest version that is available in the store? Did you check the IME/AgentExecutor logs as outlined in this post to see if the upgrade is being attempted and failing or not even attempted? You won't see an upgrade option in the Company Portal, as the upgrade is automatic not user initiated. Note this upgrade capability for Store apps of a Win32 installer type is unique to Intune, not native in the Microsoft Store, so only applies if there is an Intune application policy assigned to the device, which for available means not only assigned but that the user has clicked to install.
Feedback Hub is not searchable as it has an age restriction of Teen, this is also something on our product backlog to improve and your feedback helps us to prioritize accordingly.
