I will try to write it with my poor English
Hello everyone.
I've built a model-driven app, when sharing it with users, it shows them error messages and they can't see the app.
Error
The error indicates:
The app URL was not found or you need permissions to open it. Please check the URL and try again or contact your system administrator.
Another exercise I did was to delete the cookies, and then they can enter they cannot see all the tables, it shows only one (the one that is by default at startup) and the menu to change the table has disappeared.
I have reviewed the user roles, I have checked that the users belong to the environment and that the roles are in the application and in the users.
