Determined what the cause was, hopefully may help someone else.
When applied the new security rules needed the Implicit naming applied to the App instead of Explicit. Lot of research and work for an underscore! Gotta love programming!
- Explicit type naming using wildcard (_*)Use the "_*" wildcard to explicitly define the type of resource to apply the rule to.For example, "App_*" will apply the rule to all App resources only.
- Implicit type naming using wildcard (*)Use wildcard to define the resource or resources.For example, "App*" will apply the rule to all resources beginning with "App". This means that this rule will apply to apps, sheets, stories, data and objects.
I was just following the directions to modify the Security Rules as in the above link and left out the underscore within the rule.
I do not have an example other than when I opened the app, no base sheets showed up for anyone. Since that was corrected have not had a need to go back and change the rule. Sorry could not assist further.
