After android system update (Oxygen OS 9.0.3) Google can't reached via hotspot After the system update for Oxygen OS 9.0.3, my OnePlus 3 hotspot has weird problem.

If enable hotspot on my phone and use laptop to browse google.com,
the url is not loading.

If I use a VPN in my laptop and use the same hotspot, everything is fine (so it's not problem in browser/browser plugins).
If I directly use phone to reach google.com, no problem there too (so it's not ISP blocking).

So url filter is happening only in my phone when I use hotspot.

Could someone help me to narrow down the problem?
After another update today (OS 9.0.4) the problem got fixed!
But still it would be good to know what screw up has happened in the last update.
