For some time, Reading List in Safari on my iPad behaves in a weird way. If I open a saved webpage and just scroll (e.g. to check whether that’s an article I want to read in a specific moment), it gets auto-deleted from the list. As far as I know, there is no toggle in settings or Safari to turn that off. My iPhone however does not do this.
Has anyone an idea how I can prevent Reading List from auto-deleting entries?
I’d like to know if this can be toggled.
Because I’d like it on for my reading list 
Perhaps the articles aren’t being deleted but rather marked as read and hidden? Reading list articles are automatically marked read as they are viewed. There is an option to show just unread or all articles in the lower left corner of the article panel when viewing the reading list.
Thank you so much! I didn’t know there was a setting like this. I must have tapped it accidentally. Now, everything‘s back as I want it to be.
