It happened to me as well! I thought I was the only one. The cassette shrunk into a small dot, I had trouble opening it. I reinstalled the app, the icon came back to size, but I think it’s starting to shrink again. Wierd!
I don’t use it on my phone, only on a desktop PC. But it’s got two sizes anyway. The smaller one is there when you get into a thread and it brings the site’s name; the bigger one shows up after you roll and the thread’s name shows.
It’s not just you guys! I’ve also been noticing it on my (Android - shut up, I’m cheap) phone. I thought the first change made it look better, but now I just get the sense the icon is moving farther away every day. It keeps me on my toes!
Bug or not, it’s undeniably interesting! Is it trying to retreat, discouraged by the tiny number of visitors? Or is it drawing away slowly, trying to entice us to follow to some mysterious other location? Is it becoming an icon in another sense? Come back again to see!
