If you want to make changes to your health tasks:
Go to Plan
If not already selected, go to Schedule
Tap the Health task you want to change and a pop-up will appear. Choose whether you want to 'Edit' or 'Delete'.
Cannot see the 'Edit' and 'Delete' buttons in the screenshot above? Check out this article here.
Note: some changes are not possible to do under Edit, so you'll have to Delete the task and add a new one.
If you're still having issues editing your schedule, please reach out to the team!
