OzRunways and NAIPS for iOS require a new version. We just hit the release button on both of them and they are making their way to an App Store near you as we speak. May take a while to appear in your updates list.
No real reason given about the reason for being unable to run in parallel; other than that there are also updates to the NAIPS back-end being made.
Of course in IT nothing is impossible, but these systems are old and I am sure they did a cost/benefit/risk analysis of doing even more work to enable this and decided not to.
