Cloud Collaboration Tools & Post-Production Dynamics - Seeking Insights!

Hey everyone, I'm Ngozi, a working screenwriter, and I've been mulling over something as I prepare for my next project. I'm used to the traditional rounds of notes and revisions, often with a lot of back-and-forth email attachments and version control headaches. I'm trying to be more proactive in understanding current post-production workflows.

I've seen Frame.io and ShotGrid mentioned a lot lately as key tools for collaboration. I've personally only really dipped my toes in with basic Google Drive sharing, but these seem like a different level altogether. For those of you who've been using them extensively, how has the widespread adoption of these cloud-based platforms truly changed the dynamics of post-production collaboration in recent years? Has it sped things up significantly, made feedback loops tighter, or presented any unexpected challenges? I'm genuinely curious about the practical, on-the-ground impact.
