Yes, thank you. Your response clarifies a lot and gives me direction.
I read that privacy rules were checked server-side and I didn’t even consider the “loop” you mention.
I assumed that filtering with privacy instead of conditionals would be more data-efficient, as less data would be transferred from the server to the client. But I’m still not sure. Anyway I’m going to have to rework my structure because as you mentioned, the logic is there but it’s probably just not stable.
Thanks for your help
