How can a file be synced across multiple devices? I am able to store the data locally using binary serialization, but the user should have the ability to access it on any device at any time.
Is this done automatically by the operating system? If the user logs into an Android phone using a Google account, would local data created by the application appear on every device that Google account is logged into or would I need to implement this functionality myself?
I have considered using a remote database, but I am not so sure that is the best option. My target platforms are Windows Universal, Android, and iOS.
The closest topic I found when I researched this is "Remote Settings" and "binary serialization", but neither help in my case.
