I can confirm that!
I had to download Gears of War 4 from the Windows Store because it was distributed there. I had a terrible experience: account not logging, download not initiating etc.
In the end I had to download it on my laptop whose Store was seemingly working better and transfer the files over to the Desktop.
My experience is that WS is very fragile and much less reliable than Steam.
That something I never understood the Xbox store works pretty much flawlessly.
How hard do you need to work to screw up something that already works just fine.
