My Connect:Amp occasionally drops-out and regularly stops tracks 10 seconds before the end. It continues to play the next track at the right time and stays in sync on timing with all my other Connect:Amps, Play 1s and Play 5, but just stops playing for the final 10 seconds.
It is on the latest firmware. Every device is hard-wired. A reboot doesn’t make any difference.
My setup has been stable (since some issues last year totally coincidentally about the time of the app debacle where some of the devices moved to new firmware and others didn’t. I now update them all manually so I can monitor updates and ensure they don’t break everything) except for this one device (and the general slowness of the app everyone has, of course).
