How long did you wait until Helium accept your article in marketplace?

Tweet

Recently I have 3 articles submitted in the Helium marketplace. One day after the marketplace closed, 2 were rejected. The last one of the 3 is still marked "In process" for more than 4 days already, with no e-mail sent to me to leapfrog. Usually, how long did you wait until Helium accept your article after the marketplace close?
