New Gardena problem - ability device_info not found

My Gardena smart home account Thing is showing as offline with the following message:

Status: OFFLINE - CONFIGURATION_ERROR Ability 'device_info' not found in device 'new watering'

However the individual watering and sensor Things seem to be working fine.

Is this just me, or another change to the API?

… and it’s now fixed itself. No change to Things, no system restart, nothing… just mysteriously fixed.

well, okay!
