Hello, When trying to use the beta UI, I have something like 30mn+ load times (dealing with content updates) and at the end, everything is stuck at 1 remaining item and reported as IDLE... Seriously, do you plan to do something about this ? This is an experience killer, greatly...
Switch back to default UI and see if all the content updates. If it doesn't, see if there are any error messages in the Launcher/ Settings page (the cog icon)
