SteamingAssets with Andoid bundle

I'm having some trouble with getting StreamingAssets to load when I build my app as an app bundle.

I have some text files with JSON data in them that loads fine when I run in the editor, and when when I build the app as an apk.

The problem is when I build an app bundle to release on Google Play, the StreamingAssets no longer load.

I have tried using both UnityWebRequest, and the BetterStreamingAssets package from the asset store.
these both work in the editor and as an apk, but not as a bundle.

Has anyone else seen this? Is there some permission that needs to be on the android manifest?
Is "Application.streamingAssetsPath" returning the wrong value for an app bundle?

I just very confused here, and any help is appreciated.

Thanks!
