First,I checked several related threads,but my problem is a little different.
scenario:
I created a list in sharepoint, including "mailto","category","arrive time", and "reason". Four fields in all and all of them are needed information.Also,I made "title"field not needed information.
Simply clicking "make app in powerapps"button,I get an app with view screen, detail screen and edit screen in powerapps.With some simple change like making "created time" field unselected,I get exactly what I want,and it works perfectly in edit mode.But when I publish it and come into play mode, problem happens.
problem:
the problem is that in play mode,when I enter editscreen,fill the information to submit my new entry, arrive time field is highlighted with error message'An entry is required or has an invalid value', which just do not show up in edit mode.
Can you offer some help?
