Dear redmi,
      I updated my mi 10t today morning. After updating I'm unable to use internet in any apps but if i turn on and off airplane mode then only that app start using internet. But if i try to switch with another closed app then again app doesn't use internet and if i use airplane mode then i can use internet. Only till i didn't close that app. If i close that app then again i have to use airplane mode. Please do the needful. And tell me what should i do?
