I have a mobile app created that displays a list of attractions, restaurants, etc.
There is no sign in required to use the app.
Users can favourite (or favorite!) locations which are then displayed in a separate list.
This works by adding the attraction ID to a state list AND adding the ID to a (list) attribute for the User.
This all works and there is the ability to remove items in the reverse way.
On page load I have an action that loads the User favs list into the relevant state.
My issue is that although this works, even when a user closes the app HOWEVER when a user comes back to the app a day or so later the favourites have disappeared.
Is this an issue due to the users not needing to sign in or is it something to do with cookies or something with the app design?
