The popular comic viewing app Comixology (which is finally on the app store) has introduced an update to correct the bug for there Kindle Fire users. The bug came up last week when an update was introduced to give users the ability to download comics in HD. However the update caused users to be unable to access their purchases.
The developers have said that they’re “working their buns off” to fix the bug with the update being made available to download right now.
If you’re still experiencing difficulties you may need to manually check for an update or contact Comixology’s Twitter support account @cmxsupport.
