While casually browsing Adobe Stock website I stumbled upon this File , If you check beneath it there's written Compatibility version and it says 1.5 or above so I clicked on it and it returned a 404 page so someone else can check and confirm also also tell me what that means will be very helpful.
I can confirm the error. And it is on all those templates that I tried like that... Adobe needs to investigate. I will see if I can contact someone from the stock team... 🙂
Please find here the link that those numbers probably are referring too:
Thank you for bringing this to our attention. We'll work on getting this fixed soon!
