This app has been published and is accessible to the intended users.
The issue is that this only works for the app-owner; all other intended users are presented with an "Access is Denied" message after they've pressed the button and the app is not reloaded.
A Professional License is required for the user to be able to interact with reloads.
If one examines the AuditActivity_Engine logs after the error message is presented then you can see more information about the error; one can see that Access is Denied specifically for "Script access denied". This means that this user does not have access to the App's objects, so granting read access to App.Object_someguid will grant this user the needed permissions.
Implement a security rule that grants READ access to the App.Object_someguid.
NOTE: The figure below is for purposes ONLY. The below rule grants access to ALL app objects for a specific user and is not scoped to a specific object; do not use in production.
For production use, the App.Object_* needs to be replaced with the accurate App.Object_ID and ((user.name="SomeUser")) with the correct user name or group as required.
