Search not finding data entered via WorkApps

I have a sheet with a form. Last month I added that form to a new WorkApp to make it easier to access by our technicians. It appears that all the data entered after that time isn't showing up when I search for it. It's in the sheet. Data entered before the form was added to the WorkApp is showing up in search. Is this a known issue? Anyone else seeing this? I'm guessing something is wrong with the search indexing.
