It's the developers job to make them work and our job as beta testers to tell them if they don't.
The annoying thing is in App Store will not let us report any problems there with apps if we are running beta software, I have often resorted to using the device running current software to report serious flaws to the developers in App Store. (yeah, I know, but stuff the NDA) I have no idea if the Feedback Assistant for third party app problems pass the info back to the developer.
Our national savings bank app did not work until the day before public release despite my reporting it in both places several beta versions earlier.
