There are a number of window covering types that have tilt only capabilities, such some venetian blinds. The matter specification allows for a window covering to have tilt only functionality and attributes. When I add one of the tilt only Matter accessories to the Home app, I get "This accessory is not responding" If I go into Accessory Details and Settings, I am still able to use the tilt slider (see photo), however the target tilt percentage is always sent as 100% (90 degrees) or 0% (0 degrees). There is no granularity.

As of today my HomeKit companion app will not connect to MFi with the error "Unable to establish a direct connection to MFi. This is after I logged in with my developer credentials. This has worked previously. I am using the latest 2.0.1 companion app I have tried on 2 separate phones I have tried on a WiFi network with Internet access, and also with WiFi disabled using cellular data.
