I am creating an app where I want to prompt the user with a drop-down to select the date, i.e. they are loading a formatted file, but I want to attach a date field value based on user selection, e.g. "2018-06"
I have created a flow with a formula to provide it, and have tested with a dummy value which populates a column when I hardcode it. However, when I run the app, the drop-down prompt I set up to populate an update value doesn't even pop up! The flow just runs without prompting, even though the drop down and update value is connected to a formula.
How is the prompt not even working, and how do I get it to prompt to populate a column in the flow result?
