I have found another inaccuracy in proxyman when it comes to HAR files.

This is a HAR file generated by a Chromium based browser.
As you can tell from the headers, this traffic was http 2.0 but it's being displayed in the raw tab as if it's some mix between http2 and http 1.1.
Now I know that Proxyman isn't able to capture http2 traffic yet, but it seems it can't display it either fully either?

The expected result was to see a http2 request in Proxyman in the raw tab.
Should I open a new issue for this or keep it in this one?

Hi @BRUHItsABunny, I noticed that when I was fixing this bug too. I will update the way of building flow from HAR files in the next release.
You don't need to open a new issue, thank you for reporting this.
