I can't find TLS 1.3 in edge://flags and testing below don't show up TLS 1.3 either. See below.

My Ungoogled Chroimum also don't have the TLS 1.3 flag but testing at the above link shows up TLS 1.3. Flag says the TLS 1.3 Early Data has expired.

FF do have flag settings for TLS 1.3

All browsers using the latest version.

Anybody knows whether TLS 1.3 is still supported in Chromium-based browsers, or that it's there by default now? Can someone check your Chrome browser to verify the TLS 1.3 flag setting?

Thanks

The page you linked is no longer there
I don't know what happened. The links were from a thread on M$ Community support but I couldn't find them after I restarted Edge.
Did you test TLS 1.3 in MS Edge from the above link to see whether it's there?
Yes. It shows it enabled.

BTW, an M$ MVP member wrote that post I tried to link above and said TLS 1.3 has been enabled on Edge Chromium for a while (maybe since rollout).

On my setup The use TLS 1.3 box is not ticked but TLS 1.3 does show enabled with EDGE on the CloudFlare test page.
The last time I had an issue with TLS 1.3 was because scan https traffic was enabled on my AV. Some AV's may scan Edge https traffic but not Ungoogled chrome.

I disabled Adguard for Desktop (with https scanning enabled) and the result is the same. TLS 1.3 shown as an 'X' in the Cloudflare test site

I also have https scanning disabled in my AV
