I just looked back here to check when the API service for existing customers was being stopped. And then I went to their blog and discovered that we are getting another year, until end 2022 
well at least thats something that has come out of Dark Skys takeover.
I used to use a great app on my android phone which used to use DS API and it was always spot on for rain etc, now after the apple takeover its all stopped and now doesnt work at all.
Thank you for the update.
