I'm running into this issue and I'm not sure how to address it. When users submit a form response, the Start Date on a task in Planner is set to the day the form was submitted. On the form, they pick a date when their request needs to be actioned by, so I've used Flow to update the task due date to match what they selected. Planner is actually setting the due date to the selected date, minus 1 day.
I am OK with this as it means we get the reminder emails from Planner that we have tasks coming due soon a little earlier. However, if the user picks the date on form for the day they're submitting it (even though they're told not to, as we need 48 hours notice... sigh), the Flow fails as the task Due Date cannot be set earlier than the task Start Date, as Planner keeps setting the Due Date as the date the user picked minus 1 day.
Is there a way to either make Planner not set subtract 1 day from the Due Date to prevent this (not ideal), or for it to calculate that the Due Date is equal to the start date and automatically add a day to the Due Date to prevent the error?
Thanks!
