All new chats land on me, the administrator, instead of the Open Channel queue. Why?
Records created by WASync go to the user whose token installed the app unless the rule in Chat rules → New chats from unknown numbers says otherwise.
Because a record created without an explicit responsible lands on the Bitrix24 user who installed the app, and the Open Channel then routes the conversation to the responsible of the record. Set the rule in Settings → Chat rules → New chats from unknown numbers: Off (no lead is created for unknown numbers), a fixed person, or a rotation over a list of employees. Flows that create records at enrolment follow the same rule.
Three switches in the same place refine it: create the lead also on numbers that feed an Open Channel; create the lead when an operator writes first to an unknown number, with that operator as the responsible; and create a lead for a known contact that has no open lead or deal.
