Description

When trying to authenticate in playwright with the webkit browser Clerk never seems to be able to authenticate.
In the reporducation i am using the signIn util provided, but I have tried doing the flow manually by entering email password manually.

I think it has something to do with cookies in webkit.

Steps to reproduce:

Here is a github action testing the login and verfying the user button is visible.

Expected behavior:

Sign in button is visible after sign up in webkit browser.

Actual behavior:

The user button is never visible after signUp is called.

Hello! We need a little bit more information to be able to debug this. Does it run on your machine on Webkit and only fails on CI?

[lasseklovstad]

Hi :) No, it doesn't work on my machine.

Can you try using a mac-os runner on your workflow? (ref)
For example, macos-latest. (ref)

It works with macos-latest. Why wouldn't it work on ubuntu?
