It has been reported that Pi-hole is not blocking some Google ads when using Chrome but not other browsers. This is the result of Google using the QUIC protocol to deliver the advertisements . The QUIC protocol is actually quite useful and can make your browsing experience faster.
If you see this behavior and want to block these ads again:
navigate to chrome://flags/
in the address bar
search for QUIC
disable it

The easy way to find this flag is
1 navigate to chrome://flags/#enable-quic in the address bar
2 disable it
The annoying step is no longer needed.
In the pick you posted you can see the easy shortcut to the flag you want, in this case it's #enable-quic .
All Chrome flags have this, I think anyway maybe some don't.

Is this still necessary to do ?
Yes, or block quic on the firewall.

what about the future and http/3 which will use the quic protocol...
Google hopes you'll leave it enabled so they can continue to harvest and sell your data.

i mean as of now we can just block or deactivate it...
I don't follow what you are asking or inferring.

How is this supposed to work with http/3 in the future if I simply block or deactivate the QUIC protocol?
How is what supposed to work?
I don't know what you mean by "this", you'll need to be more specific.

i mean if http/3 uses quic protocol and i block or disable the protocol and there is no fallback, i will not get the content of the page, right? But if I allow the quic protocol, then I also allow Google to deliver their ads through their protocol.

Don't use Chrome if this is a concern.
