I've just signed up for a planet API explorer account, and after downloading my first image, I continuously receive a 429 response code when attempting to activate an item.
I'm using the activation script given here: https://developers.planet.com/docs/quickstart/downloading-imagery/#asset-activation
I'm requesting REOrthoTile item types. I've read the API returns 429 when you've exceeded your rate, however, I most definitely haven't exceeded any rate, as I only posted once today and still received a 429.
Is there any other reason I could be receiving a 429?
