Currently, there is no way to rollback to previous update, it is a shared online platform for everyone. So everyone needs to be on the same version.
You can have a look at my setup and follow it. This setup works with every function on the FBW A32NX.
I made it from the current Default profile, then move around some of the bindings, removing the ones with issues while also setting new things differently. But overall, it’s still based on the current default profile.
