The main instructions on how to install new Bibles are found on this page. However, many users have had challenges installing Bibles since iOS 13 was released. Some of these issues are related to a small change in how the sharing works. You need to make sure that you have enabled the "Equipd Bible" app in the share options. Please see this video which walks you through a demo of the NWT in Arabic being downloaded on iOS 13 and installed on a live iPhone. --- Troubleshooting In some instances the Equipd Bible app has not appeared as a Sharing option to enable. How do you fix this issue? Some users have reported that they had to delete and reinstall the Bible app several times before it finally appeared in the list. This seems to be a problem with iOS 13, so hopefully Apple will fix this issue in a future update. Try downloading the EPUB file into another program such as Documents by Readdle or the Google Chrome Browser, and then use the Share button to "Copy to Equipd Bible" from there. Here is a quick demo of using the Google Chrome app to install the NWT Chinese Mandarin EPUB file. Another user reported that no matter what they did, Equipd Bible would not show up in the list of Share Options ... until they deleted a number of the other apps that were showing in the list from their device. Almost as if there was a limit to the number of apps that would show, and Equipd Bible was further down the list. Not something I have verified but I thought I would add it here in case it helps others.
