"Your device was not found on our servers."

I can’t seem to find my device on Avast’s Account Portal, when I try to unlink my account I get, “The service is temporarily unavailable. Please try again later.”

is it still not working?

Yes it still isn’t working.

it is being checked right now. please stay tuned.

try again it works now for me.

I just had this happen when I re-installed both Avast Mobile and Anti-Theft. Do you have to reset something on your server side? I cannot disconnect and reconnect as I get an error message that servers are temporarily down and try later.
