I’ve used SONOS products for 6+ years and never had an issue.   I purchased an ARC last year and couldn’t get the product to register through the app.  I’ve called customer service a couple times, last time spending more than an hour doing the same activities (reboot, factory reboot/reset, router reboot, hardware into network).  I can not get this device to register, which means I can’t control sound from the app (which is one of the handy features).  I’m curious if I have a defective device but I’m trying to find the receipt from Best buy (think it was after last Christmas).  We are running an Eero router/wifi (aaris router) but unsure if that’s the issue.   I’m open to suggestions but we’ve tried everything….
