Yeah, it's a mess that SUM has that much less priority. It's very important tool for us. A management software should be updated before the software it should manage is.
Good to hear that for you the SUM is as important as for us. We are working hard to release it as soon as possible.
Sadly the work on the SUM can only finished after the work on the UTM is finalized. It's sort of a chicken egg problem. To ease that we've implemented that the SUM 4.1 supports already some important features of the UTM 9.2 (like backup, monitoring and licensing).
We are releasing the SUM 4.2 Beta next week. You get more information with the release. Stay tuned.
