When you create an Activity, you will have an option to announce so that parents can see it on their “Home” page. Parents are most likely not seeing the activity that you’ve created if they are looking at the Home page and you haven’t announced it.
For any unannounced activity, please direct the parents to go to their “Activities” page to see it.
Alternatively, you can also announce the activity after you created it so that parents can see it on their Home page. Simply go to “Activities”, click the gear icon and click “Announce”.
