Advanced Notification - Rule Editor New UI

Advanced Notifications is currently not supported in the new clients for the user interface component (i.e. the rule editor). This functionality will be introduced in a future release of the Compliance Kit. In the meantime, users requiring access to the rule editor can switch back to the classic client.

For reference, the M-Files Client Feature Comparison provides an overview of feature availability across client versions.

I might just clarify that the advanced notifications will function absolutely fine for users using the new UI; it's just the rule editor which is not (yet) supported.  Joonas did say that but I wanted to underline it.

Typically the rule editor is used by a subset of users, and even then only infrequently.  For those one or two times you need it you can switch back to the old client, configure the rule, then switch back to the new one.
