I'm not able to join a challenge

Here the most common reasons users are not able to join a challenge:

  1. User has not set a name. Spar requires all players have a name. This is especially common for users who use their phone number to sign up.  Do you have name?
  2. User has not verified their email. Spar requires all players to have a working email so we can communicate important billing alerts. This happens automatically when you register or link with Apple sign in.
  3. User has no chargeable card,  the card failed the $1 temporary auth, or has previous invoices that were never settled.
