Why doesn't Pinduoduo send messages automatically?

There was no SMS notification after Pinduoduo WeChat paid. Unless you pay with a card bound by WeChat and set up SMS notification, there will be SMS notification. It is also possible that you used to buy a lot of things in Pinduoduo with SMS prompts, but now there are no prompts. It may be that when you buy something on this platform at first, the system will still prompt you, but you are a regular customer and won't prompt you again in the future. It is also possible that you turned off the notification function in Pinduoduo, so you won't be reminded. Generally speaking, Pinduoduo's words, that kind of short message notification, are really overwhelming.
