Initially happy. I soon discovered XPS docs cannot be read within. Then, after their July 13 fix the password screen changed in appearance and no longer recognized my password. Went to this apps FAQs and felt #3 addressed my issue or so I thought. What if I forget my password? "Just write to us and well email it to you." Not the case! After several emails back and forth, I was advised to delete & reinstall - loosing ALL stored documents! Why have an app you have to keep paper back-up for?
