Recently one of our customers upgraded to version 9.0 and suddenly and once the upgrade completed, they reported to us that they are not able to find permission for Apps under their security roles, both system and custom.
Basically in the prior versions, the permission for App used to come under Customizations tab with the Name – “APP”
The App entity was missing in the security role screen in the customization tab, once they upgraded to V9.0.
Honestly, I did not explore much of the customization tab in Version 9.0 and when this was reported, I was kind of out of answers as to where it have gone.
Searched with the App word in the browser screen of the security role and found one called “Model-Driven App”. But was not sure about whether this referred to the same one or is it something different.
A bit of searching and finally came across this article which verified my understanding.
Verified with existing security roles and I can see the App permissions are rightly reflected in Model-driven App Entity
Hope this quick tip saves you some time
