I don't have an RPi 3 sadly enough. I don't mind waiting long at all, I had to stop the process after a while because I had to go, so I'll try again tomorrow. But in the documentation it says that it usually takes 10-30 minutes, so that's what's throwing me off. I had a really bad internet connection though, so that might've slowed downloads down, but still not sure why that'd affect the sluggish typing. Even the slowest boards should just be able to type smoothly haha.
