Awful

So slow it’s unusable, keeps freezing anytime I wanna highlight text or turn the page.

Recent issues with app

I use this app for my textbooks as a college student since I have adhd. In previous semesters it’s worked, but recently the voice over has been stopping at random spots or not reading the full page. Not sure if it’s just my app or something, but I hope it gets fixed soon.

Every time I log in, I’m rerouted back to the login page and can never access my textbook.
