Adobe has brilliant engineers and talent and some parts of XD are well built and I want XD to succeed. It makes me speculate if it's a case of the original team being moved onto other projects or management exploring outsourcing
The reason why I stopped using it was because every time I exported an asset, the image was blurry for some reason.
I do have XD installed just to view designs but I don't really design in it and what amazes me is how often it gets updated, almost weekly.
But at least XD allows you to save your design files locally. Figma forces you to use their cloud storage, which is pretty much a non-starter for me. I like to store my design files with the rest of the project, which is impossible with Figma.
