Well, looks like it was when opening the site from the gmail app. Then it stays within the app. If I open it in Chrome, it worked fine.
Yes, we should use chrome to get a good service I have also tried to use gmail app and that is not a good way to use bitsler that's why I have disabled the app for bitsler. Now I only use chrome.
Yep normally I always use Chrome but didn't noticed first I was using gmail because I had the verify my login by clicking some URL in the mail.
