Multiple times Libby has deleted my library card info and it asks for the info as if it were newly installed. Other times, the app loses all my downloaded content and it has to be downloaded again. No explanation is given. Sometimes the app cannot play downloaded audiobooks when an internet connection isn't available, which defeats the point of downloading. Once again, in Jan and Feb, 2022, Libby deleted all my library cards and downloads. This may be related to misuse of Android WebView.
