Field Mapping Errors and Warnings

When you publish a new version of an app, you can choose to keep the records from previous versions of the app. However, if you made changes to the app, you'll likely run into migration issues that you'll need to address before you can publish a new version. See below for some of the possible errors and warnings you may encounter.

Note: When you fix errors and warnings, you can choose to either accept the issue or not to retain that particular record across app versions.
