Today all my Echo devices (an Echo Show and Echo Studio and several Dots) went offline and have refused to reconnect to the internet. Ive reset the Show but when I try to log into my account I get the screen (pictured below).

There appears no issue with my wifi as other devices are connecting without issue. I had an incredibly frustrating chat with Amazon support who, bizarrely, insisted that Echo devices are not sold in NZ so of course they will not work (I bought the devices at Noel Leeming and Harvey Norman, and they have worked without issue for several years).

One issue may be that I have a legacy AmazonUK account, but I have also tried on a separate one on an alternate email at AmazonAU, with the same issue.

Any thoughts anyone?
