Hello,
I can confirm that the C SDK is currently down for maintenance right now. We are also implementing a short form so that people can officially request access to the SDK. This is a small change in process so that we can understand more about who is using the C SDK and how they are using it. This will then help guide us in the features we are able to support the community with.
Apologies for any “bugs” in the form right now, I hope the team will have these rectified soon.
Kind regards,
