Hi @KimberlyG89
I'm sorry for the confusion and do understand why it would be helpful to narrow by tag especially with over 10,000 contacts. After reviewing your account, we can confirm that this wasn't a recent change, however it may appear this way since you were using our prior editor. Due to account limitations, this is currently unavailable.
We will certainly pass along your feedback for our engineers to continue to look into.
In the meantime, you are more than welcome to add your tagged contacts to a list directly as Nichelle mentioned. As an alternative, you are more than welcome to decrease your bounces which can reduce your contacts back under 10,000. This will restore this feature.
We're currently revamping this into a new segments feature which should provide some additional flexibility. You should see some expanded functionality with the segments feature coming very soon!
