I found a couple of other threads, one of which was the same question about ten years ago, but the most recent update in February 2023 was that ad previews are not supported via APIs.
I just wanted to check in if ad previews via API are on the roadmap for next year because asset group previews were launched recently (in August 2024) so, I do have hopes that ad previews would also be supported soon.
This has been a constant ask across multiple users, so was wondering if there is any plan to support this natively?
