Issue on iOS when redirecting back to the redirect_uri with the ?code parameter attached

Issue

There is a weird behaviour when the redirect_uri attached code parameter is not of the format "schema://path?code=123" but "schema://path/?code=123" (notice the appended "/" between "path" and "?code=".
While on Android everything works fine, on iOS nothing happens anymore - the screen seem to get stuck. Even no error is raised. Took me quite a while to figure this out.

Azure has this same issue, we are happy to accept a PR for a doc update!

it's only working when setting iosCustomBrowser: "safari" - but that gets rejected by Apple due to bad user experience. The only workaround is to add the / to the oauth redirect url
