Is there a way to NOT share data between root domain and subdomain?

Hey there,

We have been using Intercom in two of our domains, the root domain, and also a subdomain website. We set up two proactive messages something like this,

First proactive message

• set Where to send as if current page URL is https://mydomain.com along with Visitor audience

Second proactive message

• set Where to send as if current page URL is https://sub.mydomain.com along with User audience

But if a user visits our website with the following sequence,

1. visit root domain https://mydomain.com, and a new conversation gets auto triggered (unread)
2. visit sub domain https://sub.mydomain.com and logged in as user, because there is one conversation is opened in step 1, and the data is shared, Intercom shows user that conversation again.

I tried a lot of different settings such as using condition as NOT CONTAIN subdomain, it still doesn’t work. Because the conversation is already created in step 1. 

So now I feel this is probably can not be solved on the rule level. We’d need to split them, so the root domain and the subdomain don’t share sessions, cookies and maybe also data.

Just want to check if there is a way we can achieve this?

Thanks
