I figured it out. With GetRasplex, if you DO click “Update Links” after making your selection, it resets it back to Raspberry Pi, but the dropdown menu still says Raspberry Pi2. So the UI is correct, but then the download file is actually the RaspPi1 file.
Since I didn’t see any instructions on the site or in the UI, I assumed the “Update Links” button was supposed to be clicked. However, after reading above I did it without clicking that and now it’s downloading the correct file.
