AnonId is being replaced

We are running into issues where the anonymous id that’s been set when a new user visits our site changes as this same user creates an account. We call Identify right after the user creates an account and before the next page loads. A user Id is set but then a new anonymous id has been set replacing the old one which breaks our acquisition reports which are typically tied to anonId. Has anyone else experienced this? How did you solve for this?

Note: our registration flow is built on vue as a SPA

Hello Christal,

I hope you're having a great day! I'm here to assist you with any questions you may have.

Would you mind sharing a link to an example user? I'd love to take a closer look and help you out.

Additionally, could you clarify if the AnonID you mentioned is a custom property or is it the Amplitude ID?

Once you provide more details, I'll be more than happy to assist you further.

I'm looking forward to hearing back from you!

Warm regards,
