Password reset not sending email to gmail.com

Hello!  I've tried every way possible to get my password reset sent to my Box account (linked to my gmail.com), but the reset email never comes through.  I have no filters in place and there is nothing in my spam, and everything else in the suggestions here failed:

  Any advice much appreciated.  I really wish there was a way to get back in my account!
