Document.write call issue - asynchronous or synchronous

It seems that I am having issues with Js document.write.  See errors below.

A Parser-blocking, cross-origin script, https://assets.adobedtm.com/b5b29a6957a8d2a24ecbacc1f61081cac98a17d6/satelliteLib-94520539f49c0b7700c84a7401ad80c9d729a3bc-staging.js, is invoked via document.write. This may be blocked by the browser if the device has poor network connectivity.

How do I correct this. According to Adobe documentation I should not deploy appmeasurement asynchronously. But then another document says that the script needs to be deployed asynchronously.. 

see links for documentation below. In the mean time what do I need to do to corrrect this error, or how do I figure out what script is causing this error?
