Great app version of New Yorker, but bookmarks disappear

This is a great app. Nice cartoon feature and clean interface, along with the always compelling content youd expect from the New Yorker. But the technical issue of bookmarks and favorites always disappearing without even accessing them has gotten a point where its very irritating. I scroll the app, find something I want to come back to later by bookmarking it, and then its gone a few hours later. So I stopped doing it. Yes I can just bookmark it elsewhere, but this needs to be addressed. After several complaints, it still seems to be in progress. I hope they have a fix soon. Thats my only qualm. I am not sure if anyone else is having this issue or if Im just unlucky.
