     - **Warning**: If you bundle one instance of a destination in a mobile source but have other instances of that destination connected to that source you might see unexpected and inconsistent data.

Segment can’t bundle multiple copies of the destination SDK and so it can’t send data to multiple instances of the destination from the browser.
