If you are using the Coach feature you must meet your xp goal every day by midnight of the time zone in which you originally created your account. If you have encountered a bug, also contact the support tab to the left of the screen.

Have you changed time zones recently?

[GeoMan2]

I never changed the time zone, I am at home. I think it is a bug. I wrote to support, but no answer till now.

Still no answer. Is there any other possibilities to contact a moderator?
