I have a dropdown field called IsSubmission_IIN and it is a Yes/No field. A button is also on the form that is hidden, if the dropdown field is blank OR if the field value is No. This is the formula I have on the visible property of the button:
If(IsBlank(IsSubmission_IIN),true,false)Or If(IsSubmission_IIN.Selected.Value="Yes",true,false).
This seems to be working in preview mode of the app but once I publish the app and try it on a form, the form loads with the hidden button already displayed, and only becomes hidden if I change the value in the dropdown to No, or if I remove the value and leave it blank again. I'm not sure what can be causing this behavior.
