I can't delete my old network on the Deco app. I get an error that it can't connect to the network. Is there a way to delete an old network that you can't connect to? 

Background: I reset my main deco and struggled to get it back added to the network. My plan was to recreate a new network (which my reset main deco easily added to) and then delete the old network. Unfortunately, that last step seems harder than I thought. Any advice? I can't delete any of the nodes either.
