@loipl @diepbuihuu The lack of testing continues to be unacceptable. This type of problem is easily caught if you test this before making a commit ... especially if you're both looking at it. This shows me that you simply aren't. I was doing a very important demo with a potential partner today, and I looked ridiculous because they couldn't even RSVP (they couldn't log in!). I am SO disappointed in you both.

@edgeprod sorry. It's my false to not testing on mobile before pushing. I don't even think this type of design error can happen. Will fix & take care next time.

Verified, closing ticket.
