I am really enjoying StepSmash so far, especially Smash Bingo. Thank you so much for creating this app.
How many challenges can I run at the same time? I have five on the go, but I can only see four of them on the Active Games page.
Thank you.
Edit:
The Workweek Hustle has reappeared. 
We currently don’t have any limits on the number of challenges you can be in at any given moment. We may add limits to users who are not subscribed to StepSmash+ in the future, but that’s not something we’re actively exploring today.
We’re aware of an issue with games disappearing after they end, before they reappear again a day or so later. That’s likely what happened to your Workweek Hustle.
