Ambient Weather setup not accepting my keys

I have been trying to install this integration for two days without any luck. I have read many posts with the same issue from a long time ago and nothing have helped. I have created several application key and when it doesn’t return an “invalid_key” error it returns a already_in_progress error resulting in a blank form as in this screenshot

This the error:

{
    "type": "abort",
    "flow_id": "c1d3d94017244be388fcc3feb76021a3",
    "handler": "ambient_station",
    "reason": "already_in_progress",
    "description_placeholders": null
}

Did you ever figure this out? Same issue here
