Background: I’ve used Amplitude in a previous company before and managed to create an attribution model that included first click + last click data on a user level.
Goal: I’m at a new company and would like to be able to stitch first click + last click UTM data before a user creates an account and link that data to the account creation User ID. Trouble is that iOS 14 might mess things up.
Question: How does Amplitude stitch together different sessions from the same anonymous user and can that first click UTM data be linked to an account creation? Or has there been some lost functionality since the introduction of iOS 14?
Thank you, I had a search of your help FAQs and other questions posed here before but couldn’t find a similar question.
