Try restarting your phone
You can also try to log off and then to log in again. That's what works for me
Try clicking the "New Version" word at the top, aligned with the logo of Mangago.
Sorry, this is can be done while reading a manga. Another is, at the very bottom of the page, there is an option to "Mobile Version"
delete your whole history. That's what worked for me
How do I change it back to the mobile version?
