Xbox
This version also brings 19.1 to the Xbox - while 19.0 has been in the Microsoft Store since its launch, it was just Windows, while we found a way to properly test the new version on the Xbox. We've fixed this now so that Xbox users will automatically upgrade from 18.9 to 19.1 if you have automatic updating enabled. It is worth mentioning that there is a known memory limit - present in 18.x - which causes the Xbox application with 4k content to crash, so please be aware.
