我有MPL集成到IOS了一段时间，已经可以正常使用了几个月，而不是一些用户已经看到了贝宝的错误说：该系统目前无法使用，请稍后再试。

I have had MPL integrated into an IOS for some time, it has been working perfectly for months, not some users are getting a paypal error saying "The system is currently unavailable. Please try again later".

任何一个知道为什么会这样。

Any one know why this is happening.

推荐答案

我收到了贝宝有关这一问题的回应如下：

I have received the following response from PayPal concerning this issue:

哪个是你使用MPL？在旧MPL过期的证书，这可以解释的错误信息被抛出突然。如果你还没有使用它，请升级到通过以下链接最新的MPL版本。

Which MPL are you using? The certificates expired in the older MPL which would explain the error message being thrown suddenly. If you're not currently using it, please update to the latest MPL version via the below link.
