Ok running want to create new rule backups as old ones not working

where has the fx been moved to, all i see in sttings now is restore.. where is the option to export/ etc rules. thanks

found it again.. under rule machine settings.

You've probably figured this out by now, but it's not Rule-Machine-specific: every app now has an export (and usually also clone) feature available on the App Status (gear icon) page. It is now a platform feature and not app-specific. In Settings, you can restore anything, though not export (their reasoning being more or less that this makes sense to have available outside the context of any specific app, which an export still depends on).
