After Upgrade, SDATA on custom entities only accessible for users with Admin rights.

We have a client currently on 2017R3 for production.

In a test setup, we upgraded  with the path:
2017R3 -> 2019R2 -> 2022R2 - > 2023R2

On 2017 R13, all SDATA feeds we're working and available to every users.

After the final upgrade, SDATA feeds on OOTB objects work fine for every users, but SDATA feeds for custom entities work only for ADMIN users.

If we give admin rights to a regular user, the SDATA feeds work, but once we remove the Admin rights, SDTA feeds stop working. 
As mentioned, those same SDATA feeds were working properly on those custom entities before the upgrade. 

Does anyone else experienced this issue ?

Thanks.
