Bugwatch - bookmarks disappearing in Android

[demneptune]

I'm using an oppo phone with the Android operating system and in Pleco the bookmarks simply vanish and I have to restart the phone to recover them. When I click on "organise cards" the app simply crashes. Restarting the phone works, problem recurs within hours. Restarting the app does nothing.

Hmm... is there any sort of a cloud backup or storage clearing function on your phone that you can turn off? Have you tried deleting and reinstalling the app? Did you install it originally from Google Play or somewhere else?
