You can create and view notes through two ways - either from contacts’ profiles, or in the Notes column of a list. When creating a note, you can tag your team members by using the @ symbol so they’ll be notified in Affinity of your note. You can also include hyperlinks, which will be auto-formatted and clickable.
To add and view notes associated with a contact, you can press on a contact's name and look for the Notes section.
Additionally, you can add notes to entities through a list.
