Hi @Peter_Loeffel,
Thank you for the additional data point and my apologies for the long response time. What you observed seems to confirm our suspicions that this was related to Sonos devices. I will merge this topic into the tracking thread that you linked to ensure you will get notified about updates. While I cannot give an exact timeline I want to assure you that an investigation is in progress. We appreciate how patient you’ve been with the process.
