Uploading Package while app is in Approval/Submission Process

When the package is actually in the testing queue, you want to be absolutely sure to notify them you uploaded a new package ASAP.  Also be sure to change the version number in the manifest or somewhere like an About screen.  Many times they have kicked back bug feedback on the older revision submission and not the current for me.  They also don't have to re-test every bug filed from a previous kickback - usually only two or three and they add to those and kick it back again with the old bugs listed as not fixed when they didn't re-test them.  And keep in mind, Roku's QA has some users in the Ukraine with what seems to be dialup access.  So if your app doesn't load in 3 seconds in the Ukraine....be sure to keep perspective on their test environment and distance from the rest of the world.
