New shelly plus 1PM does not see firmware updates. "Your device is up to date. 20220909-120354/0.11.1-g56f689f"

As in the title. This is my 9th Shelly Plus XPM on my network, so I know the process. All my other devices could find the update and apply it automatically using the Shelly's own web UI. On this Plus1PM it does not. I've tried the Shelly's web UI and control.shelly.cloud. On the Shelly's web UI the "Check for Firmware Update" button appears to do nothing.

- DHCP-assigned IP/DNS/routes

- Device is visible in Shelly Cloud so I know it has internet access

- existing device firmware 20220909-120354/0.11.1-g56f689f

I've tried rebooting the device from its' web UI, and by cutting power at the circuit breaker. What else can I try?

shelly.getDeviceInfo output:

I don't mind updating to 1.11.0 via rest calls but I can't work out the Firmware download Uri for my device shelly plus 1. SNSW doesn't appear in the list at archive.shelly-tools.de . Can anyone help?
