I wouldn't be surprised if they're struggling full-stop. Doing anything with "apple-level" polish and reliability on current-gen LLMs is a challenge. It looks great in demos and maybe even 95% of real-world use cases, but the remaining 5% tends to be embarrassing.
And it's not just a case of "the last 5% takes 95% of the work", it's more like "the last 5% is an open research problem".
