Open Issues:
- P300 Shure Audio Encryption is not backward compatible; all devices must be on version 4.1+ firmware to use this feature.
- P300 Shure Audio Encryption sometimes has a brief crackling sound on audio after muting.
- Shure Update Utility and Designer may not allow downgrading of new P300s shipped with 4.2.7 or higher due to a platform update.
- P300s with firmware 4.3 require Designer versions 4.3 and higher; not supported in versions 4.2.1 and earlier.
- P300 firmware may periodically add new properties, making the device undiscoverable if downgrading without the new properties.
- After upgrading or downgrading between MXA 4.3 and earlier releases, the device's web page may stall on the "Loading" screen.
