I was visiting my profile and thought to fill up my bio in the profile and there I saw some issues.
First, the bio box has an alignment issue.
Second, when I tried to select the date for Birthday date drop-down then the drop-down kept opening and closing in an instant. Along with opening and closing of drop-down the mobile keyboard also pops up and goes back. This thing went on going for every time I tried to select the date. And because of this I never got a chance to actually select any date.
I am using Moto G5 Plus with Android 7.0 and using Google Chrome (latest version).
