Don't merge unless your device is running Android 2.3 or later or iOS 9 or later. If you are using a device that cannot be updated to the most recent version of Comics app on Fire OS,  Android or iOS, you should not merge. If you DO merge, you won't be able to login to those apps.
 
In the super sad event that you do merge and you’re on one of those older devices, please contact our team at [email protected].
