Ok, I'll give it some time I guess lol.
I did try messing around in the relay settings a while ago. I still don't really understand how those work or what they do. Not sure if that may have caused a problem. I didn't change the NWC relay though: that is still relay.coinos.
I'll try zapping some more and see if this persists: 
You can think of relays like e-mail servers. You may be on the gmail.com relay, another person on the outlook.com relay, but you can both send messages back and forth to each other. Most apps connect to several relays by default. Which relays you are connected to determines what is in your "global" feed, which is curated by your app into "trending" or whatever other sections it may have. As long as you have one working relay, you are good, most users never need to modify their relay list and this is aok.
Thank you! So I guess it's unlikely I messed things up too badly.
And I see there are different types of relays, "public outbox" relays, "public inbox" relays "home" relays and "DM" relays. And seems you can turn them off and on by clicking the green symbols (Pic rel)
I guess I'll figure out what that all means in time. I have much to learn. Thank you again.
