Daikin AC: stuck in "Initialization" after adding, no aircon controls

[koterpillar]

The problem

I have a Daikin air conditioner unit using the BRP072C42 WiFi adapter. It is discovered by HA, but when I'm adding it by specifying the API key:

• The add window shows a spinner for ~30 seconds
• The window says "Unknown error occurred"
• Daikin device appears in the integrations list as "Initializing"
• On the home page, the device reports all the sensors correctly but the only control is "streamer", which isn't applicable to my units.
  • Turning on the "streamer" does nothing to the unit and the toggle reverts back to off.
• There are "Update of sensor.daikinapXXXXX_inside_temperature is taking over 10 seconds" messages in the logs.
• After a restart of Home Assistant, the newly added devices disappear.
