scarsonbooth Downloaded and installed the announced Matter extension today but `the system access point requests installation of a certificate` notification occurs because the Device Attestation Certificate not found. I`ve rebooted, deleted/reinstalled, open firewall ports, reviewed the logs, etc. Any others having the same issue?
scarsonbooth ah! Seems the instructions have been updated (at least the German ones) - you must use the App and click the notification and download the cert. You can not do this from the PC. Case Closed!
