You can't send a barrage for the live broadcast because the live broadcast is under repair. When watching the live broadcast, you can't send a barrage. It's not the account. You don't have to worry. In addition, when the system is maintained, modifying the head portrait and nickname will also prompt "system upgrade, please forgive me" and cannot be changed. You want to modify your personal information, and you can't modify it until the maintenance is over.

In addition to BiLi BiLi, many softwares were under maintenance before, including QQ, WeChat, Weibo and so on. Similarly, these softwares can't change their avatars, modify nicknames and have personalized signatures. There is no solution at present, so we can only wait until the maintenance is over.

Netizens speculated that the large-scale barrage suspension event test may be related to the previous policy:

It is understood that not long ago, China Network Audiovisual Program Service Association officially released 100 "Management Specification for Network Short Video Platforms" and "Standard Rules for Network Short Video Content Auditing", which set clear requirements for future short video auditing and publishing.

It is clearly stated in the "Regulations" that the network short video platform implements the system of reviewing the program content before playing it. All short videos broadcast on the platform should be reviewed before broadcast, including the title, introduction, barrage and comments of the program. Perhaps in response to this policy, many domestic platforms have temporarily taken off the barrage function.
