Hi Forum,
I decided to take the Challenge Exam to test my knowledge of all things LoRaWAN. I was 45 questions in when a Cloudflare pop-up appeared informing me that I had been blocked. I cannot see any pages under:
Please advise how I can complete my Challenge Exam and regain access to the academy pages. Thank you.

This turned out to be a Cloudflare internal problem and has been resolved.
