Crossway updated their ESV API to version 3 which last week caused a bit of a problem with the Australian Daily Prayer app and website. I have since registered the Australian Daily Prayer app with them and have adjusted how the data is pulled on the website, so now both should be displaying the daily readings correctly. The app doesn’t need to be updated as it pulls the content from the website.
If this app ever gets popular the API usage has a limit that may get hit, but I don’t think that will happen anytime soon.
