Impossible to read "sys_update_version" table from a scoped application

[nachosg]

Hello,

I need to access the table "sys_update_version" from my app, but I am running into the error: 

Security restricted: Read operation against 'sys_update_version' from scope 'x_my_app' has been refused due to the table's cross-scope access policy

I have enabled read permissions from the table configuration and I have created an application cross-scope privilege.However, the error continue appearing.

Have I forgotten any step? Is it impossible to read the table "sys_update_version" from a scoped application? Any idea?

Thanks in advance.
