Looks like when using, a
<library name="default" type="pak"/>
preloader progress bar doesn’t update, it just shows “empty” all the way while the default library loads.
To test this, I’ve used the PiratePig sample, adding the above line in project.xml (works just the same with pak or deflate), then, with Firefox dev tools disabled cache and throttled the speed to “regular 3G”.
I couldn’t find but 2 topics on the default library, so I’m not sure if this is a limitation or anything else.
Thanks for looking into this.
