Hey!
I tested this on macOS and the AdGuard extension seemed to handle Amazon.com quite well. See the video below. If there are better example pages, please let me know.
Regarding iOS, I wish I had better news. Unless I am mistaken, the way the AdGuard for Safari extension works on iOS is something Orion cannot simply leverage. I agree the blocking experience on iOS could be better, and the team hopes to improve it in the future.
