OneLoyalty: 忠诚计划与奖励

Appeared promising but after a few days, all of a sudden the Rewards widget as well as the points info on the product page and the app Settings won't load at all.

UPDATE following Dev response: The reply as well as offering this app for free are highly appreciated and I can't pretend much I suppose. However, just thinking from a Shopify point of view and our experience, I don't think a similar solution should rely on 3rd parties that may affect our website when there are external problems. I guess this is a downside of using Shopify.
Personally, I'll try to avoid apps that might impact the frontend as the customer experience is critical.

Thankfully we are a new business and yet to grow our customer base but with the reward points becoming unavailable it made me think how our customers will be impacted if the Developer were to go bust down the line, decide to drop development of the free app or impose a paid plan for use.

I believe that a customer reward solution should be super reliable and long term and ideally a built-in feature in Shopify. I know I'm dreaming...

As a feedback strictly related to the app, it would be nice if the points shown on the product page also update with the variant change.
