I’m Brian of LINER team.
Sorry for the inconvenience.
We’ve stopped supporting LINER for Safari and will re-launch within 3~4 months.
If you have any other questions, please feel free to let me know.
We checked your video.
And it seems that LINER shortcut does conflict with “The Seattle Times”
When highlighting on “The Seattle Times” please use the manual highlight button at the top-right of the Chrome Browser.
Sorry for the trouble :(
Could you please let us know which PDF file you were highlighting?
We’ll try testing the PDF file from our side.
Highlights are normally saved automatically,
So there is no “Save” button.
