i got following error when selected todays date in date picker while adding 30 days in flow using
"BadRequest. The provided 'Wait' action 'until' value '9/5/2019 12:00:00 PM' (UTC) is not supported for the 'Consumption' SKU. The maximum wait duration supported for this SKU is '30' day(s)."
Looks like it has something to do with the UTC and time zone stuff. I did this in my flow and it worked fine for me.
Flows run has period is maximum of 30 days which is a hard limit and hence the error
Better option would be to run a Flow on a schedule(may be once a day) and check to see if it is 30 days past the date and then accordingly take action
