Filing this from OTRS / App store reviews:

I adored this app up until a week after updating to the latest version! I logged into my account and saw that all my saved articles and history is removed! I’ve been saving articles and sometimes just relying on my history to do my researches and now all of it is gone because of an update! And Wikipedia is not answering any of my emails!

Like a lot of people I love finding an interesting topic on Wikipedia and just getting lost clicking link after link reading page after page of something really enticing. I save these pages to come back to later but it keeps clearing my saves and history. Idk if happens during updates or if it’s just a fluke but it’s happened about three times now and it’s incredibly frustrating. Several dozen pages I trusted to be saved just disappeared on me even though I’ve never logged out of my account. The dark light tone option in the app makes it easier to read but until I can be assured this issue is resolved I have to use my web browser to save pages to my favorites instead of trusting the app to hold them for me
