I work in an environment where I can’t use my personal iCloud Drive on my work computer so using Drafts to sync with my iPhone doesn’t seem to be an option unless I’m missing something. OneDrive for Business is my only option for using with phone, iPad, and Mac.
Before someone mentions setting up a work account I’m working on it but doubtful it can be done. It’s not considered a supported cloud storage service for our school. Not to mention it gets complicated with my phone then as we have no plans of using our mdm to manage BYOD phones.
