There is a question Facebook OAuth "Unsupported" in Chrome on iOS where there are fixes with manually redirecting to login screen and back to the original url.
But, I have situation when login button is in the iframe within popup on some page. This popup could be displayed on multiple sites.
Redirect_uri should be the page of facebook application, in this example iframe inside popup. I need it to be redirecting on the original page.
Any ideas?
Update: Even with Manual login flow, it doesn't work. It's not redirecting me anywhere after login. Just same facebook window with message "Please close this tab to proceed".
