The version of the browser you are using is no longer supported.

Hi!
I added this code to my article:
[gdoc key=”https://docs.google.com/spreadsheets/d/1ppf5EzY6gnWiC1PAi9dxZV689RLcp5mRy8tcZDWXB9E/”%5D

But above my table I get the text:
The version of the browser you are using is no longer supported. Please upgrade to a supported browser.Dismiss

File

View
Insert

Help

And then on the far right, I get a small blue “Sign in” button.
Any idea how to fix this?
Best regards
Rakel
