Hi, welcome to the community.

It depends. If the CPU load stays at 90% or higher, it might be a bug. But it drops to a certain lower level very quickly, then it is quite normal.

When you access the web UI, it needs to pull network details from the hardware in a short time so during this moment, the CPU needs to deal with different kinds of information very quickly. I am not sure why it did not display the CPU load on the Deco APP. Personally, I think the network details on the Deco APP mainly sync from the cloud service, and it is not necessary to display many details of the hardware.

As for the next firmware, there hasn't been an expected release date but normally the new firmware will be uploaded each Friday. You could check regularly on the Deco APP and the official website.

Thank you very much.

Best regards.
