Sub is connected, not available or assigned to room

I have a playbar, boost and sub in my living room. They have always worked, but Ever since the app update my sub won't assign to the living room so I can use it. The playbar is working with music that I play and tv that I watch. When I go to sonos system info, it shows playbay is assigned to living room, boost and sub are unavailable. When I click on living room, then connect sub, it says let's assign your sub to the living room. When I click on the speaker icon below the picture of the sub, my sub will play. But will not add it to the living room. I have a diagnostic test ***********.
