As of today I noticed that new package uploads claim to require the .signalBeacon("AppLaunchComplete") function in order to be certified. I will know more tomorrow if they certify my own channel's latest update but in most cases they certify anyway like when their billing code is present and working but the site claims it's not present during the analysis. If .signalBeacon crashes any SDK channel on devices that aren't up to OS 9.1, Houston we've got a problem. Oddly enough, the signalBeacon function won't even run side-loaded on 9.2 4090-4. I wrote Roku about this and am awaiting a reply.
