#sorry, not sorry ,


After latest app update, it worked well for several months. Over the last several days, the app will not open, I’ve tried to delete and re-download several times, but after one use, the app won’t open. And this last time, most of my access to books and such were restricted.

Won't load

This app worked well enough until a week or two ago. Now I just get the orange screen that says clinical key and the circular animation that indicates that it's loading. I restarted my phone and deleted the app and redownloaded it. It still doesn't work. Extremely frustrating.

Needs automatic bookmarking

I would use the app much more if it would allow me to pick up exactly where I left off reading rather than having to click through to the chapter and then scrolling around to find the section I need. Any other e-reader app I've used has this feature. Please fix this issue!
