they took the logos app, deleted some features and call it an e-reader.  I have thousands of books and I cannot make collections and I cannot even choose to view cloud books or downloaded books.  If I want to open a book, I must use the search.  I choose "title" and enter a title, and the search type changes to "related."  I Change I back and search again.  even if I type in the exact title, the book I want is rarely first in the list.  
Example: I bought five books for Lent.  They appeared in my desktop logos, but not mobile Vyrso.  I called and their answer was to delete the app and reinstall it.  That worked, but a really bad fix.  So now I have five books that I want to read from every day for they next 45 days.  I now have to remember the exact titles, open the app and search twice, sinceit always resets to "related" for each book.  It would be infinitely simpler to create a collection of Lent books and put those in the collection.  Instead, my daily reading takes twice as long as it needs to because the app is not an e-reader, to is a cludge.
Add to all this, every time I open Vyrso, I am blasted with 15 offers to join a reading community.  So I have to delete all those each day before I read my lent readings.  
Logos/faithlife is a very rich company and they have thousands of my dollars.  iBooks is good, kindle is good, why can't Vyrso even have basic e-reader features?  It is unusable.
