Proton Drive for MacOS
Today I received an offer to participate in the early beta group for the new Proton Drive app for the Windows platform. I am not a Windows user; my non-smartphone platform is MacOS. If Proton has been able to create a native app for Windows, I would expect that an identical app for MacOS would not be far behind. I would like to know how soon to expect Proton Drive for MacOS, and I also want to up-vote every other request that Proton may already have on file for Proton Drive for MacOS.
Moreover, Proton Drive would be most useful if it could interface with MacOS in such a way as to replace iCloud as a truly private, end-to-end encrypted cloud platform for synchronizing photos and videos (including metadata), messages, notes, and all other types of data that iCloud (and/or "iCloud+") can autiomatically synchronize across Apple (and non-Apple, such as Windows) desktop, laptop, and mobile platforms.

They state on the roadmap page (https://proton.me/blog/proton-drive-roadmap) that "The Windows app is further along in the development cycle." But they're already behind schedule it seems. I'm not sure, they get more precise with dates than this :/
It would be nice to get quarterly updates on their product roadmap for each service.
