Unfortunately, I doubt anyone from the JINN team will come here to answer anything

Some recent key points:
They finally announced a big update to come last February,2020:

https://nxtforum.org/profile/?u=2962) published:
https://medium.com/@DavidSonstebo/letter-to-the-iota-community-76c940cbc315Short after that Sergey Ivancheglo (AKA Come-from-Beyond) answered:
https://medium.com/@comefrombeyond/my-side-of-the-story-about-parting-ways-with-david-s%C3%B8nsteb%C3%B8-ab8d2c103c37Plus many other accussations on Twitter and Discord between Sonstebo and CFB, both founders of JINN
So, in short, after many years of promises, it seems the JINN project has stopped -if ever started.
CFB is asking Sonstebo for the money there was in the company's account to keep developing JINN and pay some compensation to JINN holders.
Sonstebo claims that he owns the company, thus that money belongs just to him. Plus he refuses to compensate JINN holders because, as he says, all of them become rich when they switched their JINN tokens to IOTA when they had the chance.
I think they've started legal actions against each other.
For more details, I'd recommend you join the JINN chat on the Paracosm Discord
