I have a feeling you do not make use of the manual method for bypassing DRM. (Instead relying on project cdrm)
It most likely has DRM, there's no mobile method to download DRM vids, see here for more info:
I ended up resubbing to the creator since she ran a sale. I ran the script again for her profile and some others. I realized the script only pulled a very small handful of pics and vids, not nearly the full page. So I thought maybe my keys were outdated but when I checked the other profiles that ran, it was able to get their DRM content... So now I'm extra confused 😅
