Echo Plus Firmware vesion "22"

[UKEchoUser]

Hi,

I am having problems with multi-room music. The alexa app says my Echo Plus needs a firmware update and when I look at the version in the app it is version "22". This looks wrong the version should be a much higher number!

I have left it on mic off for a half an hour and it is not updating.

Anyone else got a version 22?


Thanks
