This app needs a hard refresh. Why this was every deployed for use is absolutely beyond me. Do yourself a favor and just get a hardcopy of what ever book you are trying to read. The app crashes, window resizing is impossible, sometimes the book won't even load.

USER BEWARE: This app crashes once every five times I open it. There is a known issue that causes an error message to appear stating “Email address not recognised”. Even after re-starting my phone and re-installing the app, I cannot fix it myself. I’ve contact customer service when this occurs and each time the reset my credentials, which allows me access, but I still have the issue occurring! Customer service does not work weekends, so support is insufficient. I paid for ebooks that I cannot access!! Shame on Glassboxx and shame on Princeton Press for using Glassboxx to host their ebooks.

Bought an ebook on this because of class requirements. I just bought the book 1 month ago, and I cannot open the book today to do my homework. I thought it’s internet issue or anything, so I tried everything to get it work, like restarting, use other WiFi, etc. Lastly, I tried redownloading the app, now when I login with my email, it said email address is not recognized. This app literally has only one job, one simple job, and it failed. Completely trash app.

Out $25+ bucks for an unuseable digital book purchase on this horrible last century app. If your idea of fun is scrolling backwards from Vireos through 340 pages of the book to get back to the table of contents - I wish i had as much spare time as you. Have tried to get an analog book as a useable replacement but request ignored. Buyer beware! Authors of said book who theoretocally understand how book would be need to be used in the field - shame on you for participating in this scam.
