Apple has not yet responded to this centralized removal, but according to Tencent Technology, this centralized removal may be related to the fact that some applications hope to fix bugs through "hot start", rather than fixing bugs by releasing new versions, which can speed up the iteration of applications. But Apple is wary of similar behavior.
Earlier, Pinduoduo responded that there was a technical Bug in the latest version of the iOS client (buyer's version), which led to its removal in a short time. At present, I have contacted Apple officials and will put it on the shelves as soon as possible after emergency repair.
It is worth mentioning that on May 6 this year, Apple removed more than 1 10,000 applications in a single day, and some of them were re-launched after 1-2 days.
