Somfy Integration Error

I’ve installed the somfy integration from the standard integrations in Home Assistant to control my electric blinds but keep seeing this error in the server logs.

Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/config_entries.py", line 236, in async_setup
    result = await component.async_setup_entry(hass, self)  # type: ignore
  File "/usr/src/homeassistant/homeassistant/components/somfy/__init__.py", line 84, in async_setup_entry
    await config_entry_oauth2_flow.async_get_config_entry_implementation(
  File "/usr/src/homeassistant/homeassistant/helpers/config_entry_oauth2_flow.py", line 379, in async_get_config_entry_implementation
    raise ValueError("Implementation not available")
ValueError: Implementation not available```

Have I missed something or has the API changed
