2. Check whether other accounts are bound. If you use a WeChat account to log in to the WeChat health system, please check whether you have logged in a WeChat account on other devices. If yes, please cancel the WeChat account on other devices first, and then try to unbind it.
3. Try changing a WeChat account. If you can't unbind the current WeChat account, you can try to log in to the WeChat health system with another WeChat account and unbind it.
4. Contact WeChat customer service. If the above methods can't solve the problem, you can contact WeChat customer service for help and support. You can contact WeChat customer service through WeChat official account or WeChat customer service phone.
