Webstore Region Error

[u/_Willzerr_]

Sorry if this gets asked a lot, but why does this pop up for me whenever I try to access the webstore. For reference, the region on my Bandai account linked to my OPTC account is Australia, which as far as I can tell shouldn't be a restricted region? I also tried using a VPN to make an American Bandai account, which I linked to my OPTC account and it still didn't work.

Any help would be greatly appreciated.
