I have attempted downloading APKs for my phone and it would give me this error for so much as a new notification appearing on my phone... Otherwise the download would start up fine. Maybe if I had faster internet it may be better, but as I'm stuck using phone data at 5-10mb/s at maximum, I was hoping to find some sort of fix for the error.
I guess it's off to the library for attempt 4 on downloading things from Itch.
