My weather application in Redmi has been prompting "Please check the network if there is no network connection" for several days.

Please click the menu button-Global Search under the desktop to enter the network assistant, or directly open the Security Center ~ Network Assistant on the desktop. Click traffic ranking, click batch networking control, and check whether the options under wifi and traffic 2G/3G are all checked under this software (applications that can't access the Internet). If not, please check it.
