If you accidentally selected Always instead of Just Once when selecting an app to email recipes with, you can reset the default app using this procedure:
- Go to your Android Settings -> Apps.
- Find the app that you previously selected to use by default when emailing recipes.
- Scroll down and tap on Open by default.
- Tap on Clear Defaults.
Note: For step 2, make sure you select the app that you previously used for the Email action, not Paprika. So, for example, if you previously used a text messaging app, select that app. If you previously used a PDF reader, select that app.
