Just tried downloading Void. The Xbox Beta app wouldn't let me install to a second hard drive without setting it as the default location for all apps. It then wouldn't let me use that drive for apps without removing all of the apps currently installed there. I wasn't sure if this meant everything (i.e. my Steam library) or just the Windows Store stuff already on there (FH4, Sea of Thieves). So it's going on my system drive (small SSD). Really annoying. I need more storage anyway though, so I might take the plunge and buy a 1TB NVME.
That's strange, works fine for me
Could it be due to drive letters maybe?
