Can I delete LINE official accounts after I add them as friends?
Yes, you can delete LINE official accounts from your friend list in the LINE app.
The Like button and Add friend button don't work on Safari, even if I log in.
There are currently issues with the "Like" and "Add friend" buttons not working properly due to the Safari browser's policy changes. This issue is occurring with similar services as well, and not just with LINE Social Plugins.
We are closely keeping track of this issue so that it can be resolved as soon as possible.
However, note that the following configuration will allow you to use the "Add Friend" button in the Safari browser.
