S200B & S200D Switches - Connecting to H500 Hub

I bought a host of Tapo Devices to use with a recently purchased Tapo H500 Hub.

• Tapo C220 Camera
• Tapo C460 Camera
• Tapo D235 Doorbell
• Tapo S200B Switch
• Tapo S200D Switch

Everything seemed fine, but I cannot get the Switches (Either of them) to work with the H500 Hub.  Now I found somewhere that this may be due ot the localisation of the devices. The Hub was bought from Amazon US, and everything else from the Tapo Store UK.  I am based in the UK.

Is this true? And more so, what do I do in this situation for a workaround? The US Amazon Hub purchase I really don't want to send back. Is there any way to switch to a UK one?  Everything is new.

Thanks in advance for any help or advice.
