Hi guys, I have a question about Identify (which I found this post but it didn't quite answer my question)
What is best practice to merge user distinct ID when they log in?
Using Google Tag Manager, I call "identify" on every page load with their email address - the thought being as soon as they log in on a new device, they will get tagged. I am getting this error for each event though "errAnonDistinctIdAssignedAlready", so understand this might not be best practice. Many thanks!
