The Marketplace and our team have been working hard to listen to feedback and adjust their processes to get updates and products out to the public in better timeframes, along with their new prioritization method they just started recently with their pipeline. We aren’t able to say at what point exactly something got held up with either party for every item someone is curious about, but your general feedback and concerns are being heard and acted upon.
Here is a post in the main thread about the product you are concerned about being released: PA-28R Arrow III from Just Flight - #1515 by NORTMAR
