After updating as described here my Vero 4K+ does not accept infrared mce keypresses anymore. I use my Harmony with a mixture of CEC and MCE/RC6 commands to control the device, but something must have been changed in the area with the upgrade.

This is a known issue with the current test build. Fixes for it are currently being worked on and I expect them to be in the next test build.
