Age verification: Extremely bad UX + Bug

I just bought CoD and I noticed that your age verification form in the Battle.net Desktop application is not very user friendly.

First of all something with the styling went wrong. The width of the drop downs was way too small, so I could only read 20… and 19…
I had to count in order to find my year of birth.

Secondly it would be easier to just fill in a standard text field, not a dropdown. A dropdown for day and month is still okay, but not for the year. I had to scroll down endlessly…
Have you ever heard of input validation? Please just implement a text field with some basic frontend validation.

Pls fix thx
