So, I'm trying to make a homebrew race that has multiple subraces. The problem is that it won't let me add traits to the subrace.

Do you mean:

1. You can’t see the button to add traits?  Turn your phone sideways.
2. Whenever you try to save a trait the info all vanishes?  Don’t forget to designate it as a “Granted” trait.

Thank you so much! It was the first issue, never would have thought to turn my phone sideways to look for a button that hadn't been hidden for traits on the parent race!

It’s a display width thing. Lots of stuff on this site is only accessible in landscape mode. Happy to help.
