Iodé network blocking not working

Hi all!

I was wondering how the network blocker from iodé premium was working? When I activate it on a random app, the app continues to access network to update content, or to receive emails, or anything that needs network access.
On the other hand, when I use Android network blocker (directly in the settings), the apps are indeed disconnected from network.

Is this a bug on iodé app, or on my premium account, or am I not using iodé app properly?

I have a Fairphone3 with iodéOS 4.10, iodé app version 2.2.5 with a general password.

Thank you!

Hi, the topic was discussed with Antoine from iodé. The firewall was not working with data roaming (when i was abroad). It works fine now that I am back in France.
