How to integrate WeChat payments & use the WeChat Store

We have encountered so many issues with the payment providers that offer WeChat. We are a UK-based business and we are currently using Nihao - the only payment provider who was able to integrate and activate WeChat payments for us. However, they just turned off WeChat until the end of Q4.

Are there any workarounds or recommendations? Has anyone else had similar issues? Has anyone created a WeChat Store and if so, what payment provider do you use with it?

We could find a manual option but not sure what provider goes with this:

PS - we do use Shopify Plus!

Any help is highly appreciated.
