For the device that is compatible, please check that it is included in a policy that enable the Windows Update scope for Windows Health Monitoring (WHM), as described in the article above. Otherwise, once the server has made it available and it reaches OfferReady, the client telemetry that indicates downloading, installing, success and errors is not sent or processed. That is a common reason for not seeing progress.
If WHM is enabled, please reach out to me in a direct message, and I can collect some info to allow us to investigate further.
For the device that is not compatible with Windows 11, the deployment service doesn't know which devices are compatible, so it will attempt to offer to the the device, and that is what you are seeing with the OfferReady state.
HTH,
