Why is love always associated with trainee's avatar change?

Love and the reason why trainees change their avatars have always been linked:

1, the network is unstable, so it is recommended to use wifi to log in the game.

2. Delete the original application and download it again, and download the game through regular channels.

3, party maintenance or bugs, there will be situations where you can't enter the game.

4. Because the update has not been completed or there is an error in the download channel, you can log in to the game after the normal update later.
