Don't mix language and region
The language of the text and voiceover refers to the client settings, and the available servers and login methods relate to the version and account used. The Chinese localization of an article on GameWorld does not mean that it describes conditions in mainland China. Check the official website and installation site for your version. Do not apply the instructions of an international client to another regional service without checking.
Check the server before starting the game
If you are going to play with friends, compare the selected servers and versions in advance. The official HoYoverse help states that progress, characters, and purchases are tied to the origin server; data from different servers is not combined. Changing the selection does not carry over the existing command. Therefore, first agree on compatibility, and only then plan the long-term development of the new passage.
Check your account when changing device
Logging in on another device must use the authorization method provided for the version and the desired server. A blank start after logging in may mean that a different server or account is selected. First compare this data and the profile ID. Do not unlink third-party login methods without studying the official instructions: transferring between devices and changing the server are different issues.
Check the events of your version
Check the schedule, store offers and installation procedures in the official publication of the desired region. The article about the international release does not confirm the availability of the same event in each version. For China and other markets, it is helpful to include the exact name of the customer and the date the source was verified. If there is no official confirmation, keep the question open rather than passing off supposed compatibility as an established fact.
