Can I change a challenge after it starts?

1. Open Challenges and tap the three dots next to the challenge.
2. Choose Edit challenge.
3. Make your changes, for example to the description, and save.

To turn manual entry on or off, open the challenge and tap Edit goal. See How do I turn manual entry on or off?

Support can change the dates, the goal, the challenge type or the daily limit for you. Points collected so far stay when the type changes.
