Chrome on android tablet opens pop-under in the same tab by default setup, replacing current content. If time before opening pop-under is too short, it is hard to sign in.
So you mean it is still happening? If so, this would be weird. We checked and and here it is working fine. No matter if Android or PC and also FF or Chrome.
No no. It is working fine. I described why it happened on Android. Sorry for bad explanation.
