Unfortunately, we are not able to remove recent read manga from other devices. Even after removing these manga in your other devices, they will still remain in your current device.
This is a known issue with the app and our team is working hard on a fix to address it in the upcoming updates.
We are really sorry for this inconvenience. If you encounter any other issue, feel free to contact us via our in-app support center or our email email@example.com.
