Change Monthly Donation Amount
As there isn't a way to edit a subscription amount once the initial amount has been set (ex: increase from $25 to $35/mo), you'll need to first cancel your current subscription, then create a new monthly subscription for increased/decreased amount.
Log in to your personal Donor Dashboard (found through any of the Harness fundraising pages or the email receipts you've received)
Select the person icon in the upper right-hand corner
Select "Monthly Gifts" from the drop-down menu
Identify your monthly subscription & select the 3 dots to the right of it
Select "Cancel Donation"
Select the person icon from the upper right-hand corner
Select "Monthly Gifts"
Under the section titled "Monthly Donations", set your donation amount - the new donation amount you'd like to give
Select "Give Monthly"
Confirm your payment source (card on file or other), cover fee, whether/not to leave note or make gift in honor/memory
