Cocos Creator 3 SDKbox extension disappeared from store?

Cocos Creator 3 SDKbox extension disappeared from store? Suddenly I noticed it is no more there:

Interesting. I can ask engineering to have a look.

The developer took the plug-in off the shelf.

but only this one extension provided In App Purchases, what should we use for this feature now? Thanks

@slackmoehrle sorry bothering you, but our team need to decide to continue or not using Cocos Creator for our game. Our game should have In-App Purchase feature, but currently, as I understand, Cocos Creator isn’t providing this feature? Thanks.
