If you have a security app installed on your device that has a function to block ads, please refer to the following information.
Please confirm if the settings related to ad control (e.g., personalized ads for your Google account) are enabled.
If the settings are enabled, please try temporarily disabling the ads block feature, and see if you can view ads.
In some cases, ads may temporarily not be viewable, and an error may appear depending on the system.
In such cases, please wait for a while and try again.
