Internet connection issue in some apps

I just got a Poco X3 just a day ago. I don't know what happened but suddenly there was no internet connection in some apps like Google Chrome, Opera or in Google play store itself, but other apps like facebook were connected just fine. There was both a wifi sign at the top that says I don't have internet in my wifi and a wifi sign that says I'm connected.

After doing a factory reset the problem was solved, but I want to know whether this was an issue with the phone itself that I should replace it for, or was it just something related to the android and software itself that might get fixed through future updates?

 

I did reboot the router but it was the same problem. And I even tried other phones but they didn't have the same issue.
