Guys, make sure that the email you set in options is the one ‘connected’ with your phone and visible on screen where you check the phone device ID. I was struggling again with “403 forbidden” errors today, and tried logging out/restarting chrome/logging in again to no avail. BUT what I did wrong was that I decided I would change the email in the options. Once I used the original email visible in my phone, the downloader worked again!
PErhaps that is obvious to most of you, but it wasn’t to me untill today 😀
