I tried to update to Fw 220.127.116.11. I changed the URL to /beta path, checked for new firmware and the update appeared and gave me the option to update the base.
I then clicked to update but nothing happened for at least 10 minutes.
Then I refreshed the page and clicked again to check for new update and tried again to update, nothing like the last time.
Then I clicked again to check for new update and the update disappeared like I have the stable path although I have the /beta path in the settings.
How can I update manually the DP750/720 to the latest beta 18.104.22.168 version?
