Don't use the app "Books On App" you'll definitely regret it - like me..

This app is very unreliable, do not use it!! Firstly, I had to subscribe in order to be able to sell my textbooks which I did not mind. The problem started when I wasn't seeing any progress. My books were not selling at all!! So I decided to go with other alternatives.I tried cancelling my subscription and guess what? I was unable to. All the features and sections were working on the app but as soon as I go to the subscription section it becomes blank. And I tried it multiple times - I even restarted my phone but it didn't work. So I thought that maybe I should try delete my account to stop them from deducting my money but now I'm logged out of my own account(Trying to delete the account I will admit was stupid but I was frustrated and didn't know what to do) I'm unable to log back in and I even tried the "change your password" option and that doesn't work either!! It goes completely blank and you cannot see a thing. So do not use the app "Books On App" it is very unreliable and *************. If you do use it, use it at your own risk.
