Video loads and spinner spins but does not play in iOS < 14

[LittlePeculiar]

Everything works great on iOS 14+ but iOS 13 doesn't work. It loads, I get the callback methods playerReady = true, and playerState = buffering, and the spinner just keeps on spinning. I also get this error message and it never plays

Note:: I get the same error message in iOS 14 but it still plays fine.

Error acquiring assertion: <NSError: 0x600001ed1080; domain: RBSAssertionErrorDomain; code: 2; reason: "Required client entitlement is missing"> {
userInfo = {
RBSAssertionAttribute = <RBSLegacyAttribute: 0x7f8cdac10880; requestedReason: MediaPlayback; reason: MediaPlayback; flags: PreventTaskSuspend | PreventTaskThrottleDown | WantsForegroundResourcePriority>;
}
}

Please help!
