Has anyone had to support robust file flat integration? Upload -> validation (including possibly keys between files or tabs) -> UI for users to fix errors -> data integration. If so, did you roll your own or use a library or service? Thanks for the help!
I'm looking for something private and easy to use to share pictures and videos with my family. My extended family uses Snapchat and Instagram but we're concerned but privacy and tracking. Text chains? Whatsapp? What works for you and your family actually use?
