Running into an issue where the Unity Integration (2019.2.1.7250) is not populating the "Assets/Wwise/Deployment/Plugins/<platform>/DSP" folders with the Resonance Audio plugins, as they are not present in the DSP folders. The plugin is installed properly in the authoring tool; I can add the Resonance Audio Renderer and Room plugins to the appropriate busses and build banks. Also the PluginInfo.xml file in the StreamingAssets directory is getting updated appropriately. Interestingly, I was able to work around this issue locally by grabbing the plugins from an earlier Unity Integration (2019.1.4.7065) from a previous project and dropping them into the current integration, which eliminated the missing plugin errors in Unity. The concern though is that the project would not be using the appropriate version of the plugin, which may cause problems when trying to build in Xcode for iOS.
Also as a note, this seems to be an issue with all 2019.2 integrations as well as with some of the later 2019.1 integrations
