Last month, Amazon stopped selling the Echo Wall Clock because it was having connection issues that caused it to randomly disconnect from the Echo device that it was paired to. The Echo Wall Clock is now once again available to purchase. Amazon has pushed out an update to existing clocks that should fix the connection issues, according to The Verge. The software update should be pushed automatically to the clock through the paired Echo device. My Echo Wall Clock, which did have the connection issue, hasn’t disconnected in weeks, so it does seem like the problem has been fixed.
