Right, i understand.
I tried in a 4th environment right now and replicated the issue again.
This time i tried on a fresh WP install from https://wpsandbox.net with only Elementor and WP Custom Admin Interface.
However, in this case it didn’t worked even with Elementor disabled.
The wpsandbox.net install has a custom item on the admin toolbar that shows when the website will expire.
Which i think indicates where the conflict is: custom admin toolbar items from some plugins, such as Elementor.
