Amazon Echo Control Binding OH3: cannot find amazon smart plug

Hi, I have 3 amazon smart plugs that I would like to integrate into openhab via the amazon echo controll binding. This is not a problem with two sockets, but the third is never found. I only get “Alexa Guard on AmazonSmartPlug3” displayed.
I’ve already cleared the cache, but unfortunately that didn’t work either.
Does anyone have any advice for me?

There was a bug in the release version but that has been fixed in the SNAPSHOTS.

I have tried the snapshot binding. Now i have channels but the device is still missing. Is there a cache or other files that might already contain the device?

I am currently having the same issue. Seems to be affecting Echo Glow devices as well - just installed the latest snapshot for Windows.
