# Frequently Asked Questions
# How can I see how many chapters I've downloaded?
This can be done by enabling Download badges under.
Enable it by going to→ → DISPLAY section then checking the Download badges option in the bottom.
# Some covers are white after restoring from backup
The URL to the cover has probably changed. To fix this, refresh the metadata of your library.
Refresh your metadata by going to→ → then pressing Refresh library metadata.
# How do I ignore chapters from certain scanlator groups?
Every now and then you find a manga that is translated by more than one group, because of this you get multiple releases for every chapter in the manga. To fix this the easiest way is to change sorting to Total chapters. You won't see any changes but, when you start reading you'll automatically skip the duplicate releases.
Change library sorting by going to→ → Sort section then in this case selecting Total chapters.
# Why are some images not displayed?
Aside from network issues, it could be because the images are too big or that the decoder doesn't support that image type.
# What happened to the simultaneous downloads feature?
It was removed to prevent IP bans caused by too many requests. We know that speed is being sacrificed but it's better than not being able to access a source at all.
# Downloads are unstable
Be aware that it could be a network issue on your device or on the catalog you are trying to download from.
# Can you make it possible to store manga on both internal storage and external SD-card?
At the moment, no. You could try using symlinks but that requires having your phone rooted.
