Here's a picture of what we're experiencing to clarify what is happening. I don't have Growing Together either. I'm unsure, if it wasn't a deliberate base game change, why we're suddenly seeing 'Check in with _____'. As you can see, it replaces 'Ask about Day'. If people who have the Growing Together add-on aren't seeing this, then it's a legit bug, I guess?
Thanks for the picture @Crayola4321
I also do not have Growing Together, as you can see from my list of packs in the first post. I do have the latest patch, 1.96.365.1030, and that is also shown in my first post.
@MoonlitexAngel I don't know why your game still has Ask About Day but we didn't do anything special to get Check In On. It was just part of the update. I'm as puzzled as you probably are.
