I believe that we have been suffering the same bug, although with a WKWebview.

Some metadata that hopefully will help you locate the error.

We started to get negative reviews around 2 months ago. Some users can reliable reproduce this every 24h or 48h.

We added a log statement on every request using a WKNavigationDelegate that will check if the login cookie was present and also print getAllCookies.

What we have been able to observe is that there is a ~30% chance that the first requests will not have any cookies, or at least they won't be available in the NavigationDelegate. After the third request or so cookies are sent.

I took a look at the webkit source code and it seems that the cookie initialization is async. Perhaps this is simply a race condition?
