How to break links to other spreadsheets? - Calc

[Albireo]

When I open a new spreadsheet, the message appears .:
Security warning: Automatic updating of external links has been disabled.
There are three options

• Allow update
• check “OFF” the message
• Help (which didn’t help me at all)
  My desire is to break all connection to other spreadsheets
  Is it possible?

Menu → Edit → Link To External Files.
Then it will show a dialog window where you can see the external links and a button labeled as “Break Link”.

How do you get rid of the warning permanently for a local file in the same directory?
I want the data to ALWAYS BE UPDATED ON OPEN

Sometimes the data shows and sometimes it’s ERROR
