About that...I have a tutorial (taken from an old beta thread) to fetch beta links:
How to capture the update.zip file to share with other people: 1. Download HTTP canary app from playstore 2. Open HTTP Canary app 3. Start the update by pressing "download" and don't pause it 4. Go back to canary app and start it and it will grab the link for you
