Well, I plugged the lens in this morning using the Viltrox app, and it showed it was version 1.08, and to upgrade it would be 1.07. I clicked proceed, and it went back. I didn't see 1.08 available at all. After I upgraded the first time, I noticed my camera froze when I mounted the 55 to it. I've been letting it go to sleep on my desk and waking it and it's back to normal.
