I installed the official Reddit app and went on it to see what the old place was looking like now. My inbox was filled with spam. The “home feed” shows subs I never subscribed to. There are so many ads. Between the ads and the the extra subs in the feed, it’s hard to just scroll. I also noted a lot of spam in some of the subs. Maybe they are subs with no mods? I’m not sure what’s up with that.
Something similar to this happened to me. Saved a comment in a sub that I no longer care for, but the comment was deleted or removed later. Now my saved feed has a blank comment from a deleted username but it’s still linked to that sub. Cannot unsave it.
