As i know it OneMesh should be available on both units but I can only confrim US products, as this specific community is focused solely on the US region. I can try to help but you may have better luck on the Global community that services other regions and who's management team know these regions and their products better. That can be found at https://community.tp-link.com/en
If you would like us to try to help the best we can please provide further details into your experiances with OneMesh not working and what you have tried to resolve it.
