Even if you assigned Sub-Queues to a Queue, it is still necessary to set up filters for that Queue, in order to cases to be assigned to it.
Let’s take this set up as an example:
The Queue “Instagram Influencers” has 3 Sub-queues assigned to it.
If the Queue “Instagram Influencers” does not have any filters, no cases will match it. Therefore the cases will also not match the Sub-queues.
To have the cases assigned, simply create a filter for the Queue "Instagram Influencers". It can be as simple as choosing only Instagram as a source channel to be routed to the Queue.
Later on, these cases would be routed based on the weight of the Sub-queue they match.
