iOS issues with Presentation

Hello, everyone,
I've just started using Presentations from Blackmagic Design Cloud, I'm really enjoying it because the interaction with my clients is fast and efficient!
However, I've had 2 clients who couldn't open the videos on their iPhone, it kept loading forever and I couldn't get out of it. If it's on an android phone it works and if it's on a PC it works, even on a Mac it works, the problem seems to be only on iOS.
I'll add 2 screenshots so you can see what I mean.
Does anyone know if I'm doing something wrong or if it really is a bug?
Thank you
