MyChat client applications have a special section for important notifications:

 

Automatic notificatons in MyChat Client
 

MyChat Server can periodically publish messages regarding available features, information about getting technical support from developers, and other helpful messages..

 

By default, this option is on. If you disable it, then this section would contain only default messages: how to contact support team, and how to install applications for iOS/Android by using a QR code.

 

NB! Disabling automatic notifications works only in commercial versions of MyChat Server.
