Video (HLS) quality on website does not switch on iOS 16.5

When streaming HLS files in the iPhone/iPad browser only on iOS 16.5, the bit rate does not switch. The lowest quality bitrate is always selected regardless of the communication environment.

This does not occur on iOS16.4 and iOS16.6(beta) in the same communication environment and on the same device, and the bitrate switches according to network conditions.

Has anyone else experienced a similar event? Also, does anyone know how to remedy this issue?
