Yes, I wanted to avoid creating confusion. I figured I would mention it and if the poster wants to know more, they'll ask.
EDIT IN: Also, to both OP's above, do you use a Third Party updater app other than Software & Updates or Software Updater than what comes with Zorin OS? Might help narrow down the cause. Thanks to Zaba for bringing that possibility to light.
I installed the 20.04 Ubuntu update and I want to know if with this OS I'll be notified with the upcoming Zorin OS 16 update. Do you know if this is going to happen?
