Hi @sirensimo7. I see you have three separate threads about Arduino IoT Cloud and CORS. They all seem very similar to me, but I'm not knowledgeable on this topic so I could be wrong on that. Are these three distinct questions, or are they all about the same thing, but worded differently? If they are all on the same topic then I'll merge them into a single thread so that we can consolidate all the discussion to one place.
