I have a MS Access 2016 web app that I am trying to modify the record source. Typically I am allowed to choose from a drop down list of all sources. Now the drop down list does not work at all. I noticed that this is true of all forms. It is also true in the sample web app so the condition is related to a larger environment than just my app. The apps are hosted on Office 365 Sharepoint.RecordSource screenshot.zip
