Hello, what you want to ask is why the WeChat credit card icon turns gray. The reason why the WeChat credit card icon is grayed out is the large amount of picture data. Wechat takes a long time to receive. In order to improve the user experience, WeChat will first show the buffered text information to the user. By default, the picture will be displayed in gray first, and then displayed after receiving. Therefore, the reason why the WeChat credit card icon is grayed out is the large amount of picture data.
