### 1/5 — Fix your username and password

*2022-04-12, version 1.5*

I wanted to use this app and downloaded it thinking this might help me with me reading but when I opened it it was showing I needed a user and pass I put a random one since of have never used this app before and it said it was wrong you need to put a sign up and log in option. I cant even use the app…

### 1/5 — I was exited until…

*2021-08-25, version 1.4*

I was exited to read extensive reading with BT21 cause I’m a big fan of BTS and BT21 but when I opened the app it said username and password so I went ahead and enter a username and a password but when I clicked “enter” it said “incorrect username” so I putted another password and a username and it said the same… If you can fix this maybe I can give it a better review. -unknown 11 y/o
