You can upload files to the popular GoFile site from mobile and share the URL to anyone to download, can share Admin Code(AC) to delete them if needed. This app got approval from the main API provider, GoFile team (https://gofile.io/api). If you face any issue please share with me in the comments or contact me over email. Feel free to suggest me new features, will check the feasibility and develop it and will let the community know the idea is from you.
