I'm having to uninstall this now. I've seen this too many times, often taking many weeks to "re-show" the issue. Basically, you delete all or some of the entries (in my case, its the whole lot), and for ages, they are gone. Great. But then you come back some time MUCH later, and every single one of your previously saved reading list has come back! In my case, some things have come back from the end of 2019 that have already been deleted several times! Where is it keeping this stuff? Why is it bringing it back? I otherwise love it, and it looks very smart, but this behaviour is just now a complete deal breaker.
