"Delay Posting" is not recognized when course files are added via Insert > Link > Course Links in Safari 13.1.2+
Instead it should keep the announcement locked until the unlock date.
Use Insert > Document > Course Documents instead, or use Chrome or Firefox.
Steps to Reproduce
In Safari, create a new announcement with some dummy text
Link the text to a file using Insert > Link > Course Links > Files
Set the Delay Posting option to some point in the future
Save the announcement and see it posted immediately
