I have an existing SharePoint Add-In that is in the Office Store. When the Modern Libraries came out, the app is broke and user's can no longer access the Lists. The views break and the settings page breaks. SharePoint Re-Directs me to https://mysite/undefined/_layouts/15/AccessDenied.aspx
. -- Notice the /undefined which should be a reference to the web my app is living on.
Before it re-directs me, it shows a couple other errors in the Developer Tools, but go away too fast before I can read them. So it is apparent the authentication mechanism in SharePoint Add-Ins is not working with new Modern Libraries (as it works with I go
back to classic mode).
Is there a plan to fix this by Microsoft? Is this a well known thing?
