I’m new to the forum and can’t figure out how to navigate to the question I posted yesterday; but I’d like to add that the problem I’d encountered with the 800 error code and failure to update must have been an internal issue with the Sonos website as it self corrected this morning. Today I was able to successfully get my app to update and properly set up my boost. I would add that the Sonos2 app does not properly reflect the procedure for installing the boost.
