Hi! I understand that you are having trouble connecting your Poco X3 to your MI account. Here are some troubleshooting steps that you can try:
1. Make sure that you have a stable internet connection. You can try restarting your Wi-Fi router or mobile data connection.
2. Check if your MI account credentials are correct. You can try logging in to your MI account on a different device to make sure that your account is working properly.
3. Try clearing the cache of the MIUI system launcher. You can do this by going to "Settings" > "Apps" > "System launcher" > "Storage" > "Clear Cache".
4. If you are still having issues, try resetting your phone to its factory settings. This will erase all data on your phone, so make sure to back up your important files before doing so.
If none of these steps work, you can try reaching out to the MI customer support team for further assistance. I hope this helps!
