I also have it, this came with an update of the deco app.

  @VCL Yeh, my gut feel was the latest update (app or firmware) possibly introduced the issue.

  @NeilF Will support pick up on this new issue/bug?

  @David-TP The problem with this behaviour is it introduces a needless click.

If - as is probably the case for most people most of the time - they have no one one their guest network, they simply want to see what the devices are on their primary network, which they currently have to click into to see.

IDEALLY, if there's no devices on the Guest Network, the primary network should be automatically expanded.

It's simpler and slicker.

HECK - Just add an option to offer this behaviour, such as [x] Expand Primary Network if no Guests
