Google Nest Hub - Initialize fails

Hi, Noticed since I installed .137 on my C8Pro that some rules on RM fails. I have traced it to the Initialize command to my Nest Hub (Fuchsia). Just performing an 'Initialize' on the device, from the HE device page, I noticed green activity circle on the top right just continues and never stops. Any command after this command in my rule fails to execute so the whole rule fails. I have checked to make sure the ip address of this device is the same as shown on the device itself, and have re-run the discovery process several times in the Chromecast Integration app. The HE device info page shows the status as idle. Turned on debugging and the log only show 'initialize...', also tried rebooting the Nest Hub but didn't help.

My Nest Mini's all work as normal.

Can anyone help?

Thanks
Ian

Correction. The green circle is NOT happening from the device page but from the Rule Machine executing a Test rule 'Run Actions'.

Did you try rediscover in the Chromecast App?

Yes I have several times
