Suppress Date on Sticky Post

Hi:

Our site is at https://www.stopsexistremarks.org/development/ and I’m working off of Sandbox.

I’ve read everything I could find about suppressing the date/time on our sticky post, which appears at the top of the front page. (This is the best advice I could find, but didn’t work for me: https://www.ads-software.com/support/topic/251612.)

Any other ideas about how to suppress the date/time on the sticky post only?

Thanks in advance.
