That’s really weird… I got the exact same message 4 hours ago (so around the same time you posted this). I wonder if they just sent this to everyone who hasn’t updated in awhile all at once. Tbh, it’s kind of annoying. Like if one of my readers told me they liked the story and missed it because it was September since I last updated, then I know someone is excited for it. This is just some dumb automated message that doesn’t actually care what I do.
