Patch My PC Cloud shows all filters, not just those for the "Windows 10 and later" platform. Thus, we're seeing filters for macOS, iOS, and Android, which are clearly not applicable to PMPC and clutter the interface. When you assign applications in Intune, it only shows your filters for that app's platform.
(And this issue is made worse for us specifically because we have identically-named filters across different platforms since Intune shows the platform when editing filters, and when applying a filter, it only shows you relevant ones. But in PMPC, we have four different filters called "Corporate" without knowing which one is the "Windows 10 and later" filter)
I've attached screenshots showing the discrepancy between Intune and PMPC Cloud.
