Does anyone here use a hosted, UK/EU/Switzerland-based alternative to Dropbox in a business setting? We tried out Proton Drive, but its sharing and permissions model is too basic for us — every folder has a single owner who is the only person who can share anything within it. We need to be able to do things like saying “this folder can be read by anyone in the design department and written to by design managers, and anyone with read access can also create links to share files within it”. We’re not interested in a self-hosted solution.
