When I open the Sonos app on my phone, the app says I need to install an update before proceeding (even though the update applies to a piece of hardware I don't own). So I proceed with the steps to perform the update and...the update never progresses beyond the first step...it seems "stuck" even after 5 minutes, when the update screen tells me it should take 2-3 minutes. The system will not update, so I can't actually use my Sonos for music. It's plugged into my TV via optical cable so I can listen to the TV with it, but the entire reason I purchased two Sonos playbar/sub systems was because of the streaming and music function, which is now non-functional. Please help.
