Lost a lot of orders, give up RevenueCat

In previously effective purchases, the recent submitted version is unable to retrieve the products, and I have not made any changes to the configuration.

Hey ​@wang-zhilin-617149,

The error that you’re receiving in your first screenshot is forwarded from Apple, possible things that may trigger this include:

• Apple server is down (more common in sandbox than production)
• SKErrorUnknown
• SKErrorCloudServiceNetworkConnectionFailed
• SKErrorCloudServiceRevoked
• An SCA purchase flow was initiated.

We usually recommend retrying the operation to see if the error will clear but if you are receiving it again and again, it’s likely that one of the above things are causing it. 

Regarding the configuration error, we have a handy list of common issues here: 

• Why are offerings or products empty?

All of those are definitely worth checking out, but if you have not made any changes to your configuration, I’d double check the Paid Applications Agreement and the tax and banking forms on App Store Connect and make sure that none of them have expired, and all are signed and up to date.
