Starting June 3, 2025

We have started changing the platform determination method for ad spaces within the LINE app and apps provided by LY Corporation. The changes will be applied gradually. This change aims to improve ad management efficiency by making platform selection more intuitive and straightforward.
The changes are as follows:

(Before)
Ad places that appear on in-app browsers: web
Other ad places: app

(After)
All ad places within the app: app
*Ad places that appear on in-app browsers will also be considered as app.

The impact of this change is as follows:

• If you have specified "Web" only in the platform for device targeting, ad delivery will decrease because fewer ad places will be categorized as "Web" within the app. To continue delivering ads to the affected ad places after the scheduled date, change the platform to "All platforms (web/app)."
• If you have specified "App" only in the platform for device targeting, ad delivery will increase because more ad places will be categorized as "App" within the app.
• If the platform is specified as "Web," delivery volume will decrease, and if specified as "App," delivery volume will increase. This may cause fluctuations in platform-specific values in performance reports.
• If you are using the following tracking parameters, the values may fluctuate.
  {isApp}: The value for "false" will decrease, and the value for "true" will increase.
  {deviceAppType}: The value for "web" will decrease, and the value for "app" will increase.
