Internal Server Error when enabling Anti-Theft

I keep getting an Internal Server Error when attempting to enable the Avast Anti-Theft feature on my new Samsung Galaxy S7. I’m attempting to enable this feature from my desktop PC at home. I seem to have this feature enabled on the phone but it does not show up on the Avast web site. I also have a similar problem with the Premium, it shows up on my old phone but not my new one. Is this a known problem or perhaps I’m just not doing it right.
