I no longer have the STATS icon on my Home Page when using my laptop. There's a hint of a dashed line there instead, not clickable.
Stories that I tagged as #Humor don't show up in Humor anymore. A story I wrote with the word Christmas in the title and in several tags doesn't show up when I search the word "Christmas" on Medium (but lots of old Christmas stories from 2016 and 2017 do).
One of the comments I published on another writer's story showed up in my own published stories list and my stats. Bizarre. (I deleted it.)
I also don't see some writers I follow who I know still write regularly, although I didn't unfollow them. I assume some other readers don't see me anymore either.
So you're not alone, Susan. It's a #Medium mystery. :)
