About iOS14 support
Overview
iOS has a function called IDFA (Identifier for Advertisers) that identifies the user's device.
Up to iOS13, IDFA was available by default unless the user restricted their ads to personalize their iOS settings.
With the release of iOS14, IDFA requires explicit user permission to use.
(According to Apple's announcement, this support will be available from the beginning of 2021.
Reference：Details for app privacy questions now available )
When AppTrackingTransparency permission is added to the app, an alert requesting permission to access and use IDFA will be added, and the user will be allowed to specify permission.
