Wechat can't send red envelopes. What happened?

If you use a vivo phone, WeChat can't send a red envelope. It may be that the WeChat account is abnormal. Suggested entry: I-Settings-Help and Feedback-Feedback-Red Packet, Payment, Transfer-Red Packet-Fill in "Questions and Comments" and "Contact Number" and submit. Tencent will contact you as soon as possible after dealing with your problem.
