Thank you for submitting APPNAME_HERE. We have reviewed your application and have determined that it cannot be posted to the App Store at this time becau
We ran into the same issue. Apple doesn't only inspect your M3U8 file to ensure it complies. They also monitor your streams to make sure they are what you say they are. Our stream turned out to be higher-than-64K -- because we didn't factor in the audio bandwidth (a careless, but important oversight). Remember that 64K applies to the entire stream: Video + Audio <= 64000.
If you are in doubt, Apple also offers the same stream-monitoring software. If you ask them, they will provide you a link to it. At least they did to my group.
