Payment deadline has passed but a member will attend og did attend.

If the payment deadline has passed on an event but a member needs to pay, for example if the member participated in an event but didn't pay or wants to participate.

Then it's really easy for an admin/coach to edit the event so the member is marked attending. Then an unpaid payment request is created under the ,,Unpaid'' buttons in the app and the member should get a notification about that.

It's not necessary to extend the payment deadline on the event so the member can pay, he can pay if you marked in the event that he is attending.
