Is the capacity metrics app supported? How?

We run F64 in the North Central region.  I have a two month outage in the "capacity metrics app".  It broke at the start of November.  We spoke with the Mindtree organization and were given two different ETA's for a fix, but both of those dates were missed.

This app seems to be very buggy, and needs a great deal of support, yet we can't figure out how it is being supported.  The contacts we have at Mindtree seem to be unable to give us accurate information about these outages, and their ETA guestimates are totally unreliable.

The capacity metrics app is pretty critical to PBI customers.  While it is one of the most unfriendly admin tools I have ever used, yet there is no other tool for managing the (expensive) resource hogs in Fabric, like pyspark notebooks, vnet gateways, and gen2 dataflows.

So a two month outage in this app, it is crippling to Fabric customers.  I have never seen another cloud-hosted product where this would be considered acceptable.  For some reason this Fabric SaaS gets free rein to be extremely buggy, and to lack any sort of communication or accountability.

Here are some questions about this app:

- Who should we be contacting to get our metrics app fixed when it is broken?  ... I have been using the support tickets in the admin portal but these tickets don't actually go to Microsoft.  They go to the Mindtree partners who don't seem to have any awareness of our outages.  The tickets result in a lot of second-hand miscommunication which is doing more harm than good.  (eg. ETA's were shared with us, which were probably not even from Microsoft to begin with)  

- Where would these outages be published?  Should we expect to find them in the "known issues" list?

- How are the versions and lifecycles expected to work?  Is there any place I can find a table the historical list of versions, and the version numbers that are currently under full support?  I believe I'm still on a recent version with full support (v.1.2.1).  But knowing how rapidly Microsoft iterates on this buggy app, I'm guessing there are other versions as well.  If someone can point me to reference material that lists the versions of the app (including current version and supported versions) then that may resolve some confusion.  I have not seen such a thing, despite many attemps to find it in the past.  The version number that I'm using "1.2.1" is hardly found in any of my searches.  (image below)

Any information would be greatly appreciated.  I have often wasted a lot of my amount of time trying to resolve the bugs in this app, and I'm hoping to reduce that time in the future.  I appreciate the assistance from Mindtree, but I've found that they are unlikely to know anything more about the bugs and outages than the customer knows.  Their back-end PG (.. "power bi administration"?) is ultimately the weak link.  The Mindtree engineers may be eager to help, yet they are unable to do so if the PG is not being supportive, nor providing accuracy in the back-end ("IcM") channels.
