Twitter does not redirect the user back to our server if we set force login to true in Mozilla, Safari and few other mobile browsers. But works in Chrome.
I can confirm we are seeing the same issue. Internet Explorer 11 also fails.
Chrome seems to be the only browser that works.
Thanks for the reports - we are investigating now.
We believe we found the issue - please let us know if this is working for you now.
Working as expected now, thank you for the prompt response and fix!
It is working for us too. Thanks.
Seems to be happening again.
