Hi @Tobhiyah Green, thank you for your input! We appreciate it and use it to give our teams thinking points to be considered in the future.
Our tutorial about Visibility Groups can help you achieve what you're looking for (except for activities that aren't linked to a Lead, Deal, Person, or Organization). Check out our Academy video too for practical examples. 👩🎓
If after that you still have questions, please reach out to our Support team, who are able to do all the necessary troubleshooting and advise you.
