iCloud Family sharing on Windows computer
I currently have an iCloud 2 TB storage plan that I have integrated with my Apple devices. One of my family members has a Windows PC and an android mobile phone and she's been looking for a could service to store her photography data. We were thinking on creating an Apple ID for her, upgrade my storage plan to 6 TB and then use Family sharing to add her to my plan. However, I fail to find consistent, straightforward information on whether this is possible or not. Ideally, she would have her Windows PC and mobile phone directly uploading her data to iCloud, similarly to other cloud services (Dropbox, pCloud, etc.). Is any of this possible? Thanks.
