Blizzard has blocked some phones from accessing Diablo Immortal following bug reports. Xiaomi and Samsung Galaxy phones with Exynos chipsets are seemingly affected, and Blizzard has posted a list of affected devices on Reddit. The developers have discovered a fix that will be released later and require a new download. A review of the open-beta PC version of Diablo Immortal notes bugs such as blurriness in 4K, inventory control problems, and unnecessary zooming that were inherited from the mobile version.
FYI – A fix has been discovered but will require a new build to be generated and thus a new build to all new players. We will update on timing once we have a better idea on when this will be completed.
