So, I download Mitch to my phone off the website, and it says it's version 2.3.3, but when I load the app itself, it says there's an update available from 2.3.2 to 2.3.3. It can download that fine, but when I go to install it from the app, it just crashes. I'm not on 2.3.2, it should've downloaded the most up-to-date version, so 1. Why is it saying there's an update, and 2. Why can't it install the update?

Thats an issue but it isn't problematic as long as you downloaded the 2.3.3 from f droid you are fine also ignore the update notification
