What is dialog archiving?
Dialogue archiving is an internal WhatsApp mechanism that allows you to reduce the load on your device. The dialogs in the archive are not processed by the application in the same way as active dialogs, which just reduces the load. When the number of dialogs in WhatsApp becomes more than 100, then 101 of the first dialog goes to the archive, while if a message comes to 101 dialogs, it leaves the archive and becomes 1 active dialog. That is, it turns out a kind of circulation of dialogues in WhatsApp,
To prevent archiving of the desired dialogs, use the function: \ disableDialogsArchive: true
