Changing the theme for android plugins ( primarily prime 31)

Just in case anyone needs reference to know what I’m talking about here is unitys own document on the basic theme implementation : Unity Blog

Hello Unity Devs, I have been exploring this for the past two days and have come up with no results . In order to be featured on google play an app must utilize the latest native android UI configuration available to the given device OS . Our app works fine and utilizes this theme in all the native android based functionalities however the reviewer brought to our attention that there was one place we used outdated UI and that was in the Facebook sharing menus .

This is the only place we have this issue and I keep on modifying the manifests in an attempt to fix it but copying the correct theme tag has not been working when I copy it to the plugin manifest or the or by modifying it as unity states in the default manifest theme .

So my question is has anyone been able to update the Prime 31 or other plugin theme using the manifest tweaking method or is there something else I should look into in order to get this done ?
