Hi, 1,4,5 and 6 worked for me. By 5 and 6 from GD I get to see the files and can then use the GD download button, just as in the email you send me. I’m on Windows 10 with the latest updates installed and on Chrome browser.
If you want me to test more I’m more then happy to do so. Ofcourse we have a time difference of 6 hours, so my answers may come a little bit later.
I looked at the results from the others and there does not seem an obvious denominator between us.
Good luck!
