Why did the payment fail on Apple's mobile phone Meituan?

There may be a problem with the official system of Meituan or WeChat payment.

Failure to pay may be a problem with the official system of Meituan or WeChat payment. It is also possible that the payment method page has been folded, and users can view all payment channels by clicking to expand more payment methods. If payment can be displayed, but it can't, users can check whether their network settings are turned on, or whether the signal is poor and the network is delayed. You can solve the problem by switching to a smoother network.
