Thumbnail Path substitution on Marshmallow

Hi Everyone. Has anyone here had any luck with using the Advanced Settings for the thumbnails path substitution since switching to Android 6 and Kodi 17?. In the past for both my Minix Neo U1’s and even a couple of old MyGica’s I had always put a 32 gb Sd card in the box and written an Advanced Settings file which I placed in my Userdata folder and they have always worked like a charm saving all the Thumbnails to the External SD card and not the Internal Card. I have written them to work for both regular Kodi 16 as well as the Minix-xbmc. Since switching to the new U9-H’s which run on Android 6 Marshmallow and running Kodi 17 I have tried several different ways to get the Advanced Settings to work to no avail. I had always just put an empty folder directly on the External sd card such as ‘kodi_data’ and directed the Path Substitutions to that folder and it has always worked. Now to my understanding may not work in Android 6 because of permissions. It has been written that the folder on the external sd card should be in the Kodi’s App folder. So I have instead put this folder and changed the Path Substitution to redirect to the kodi folder that the Minix automatical puts on the External SD card instead of the old path. Here is an example of some of the new Path Substitions that I have tried:
<advancedsettings>
<pathsubstitution>
<substitute>
<from>/storage/emulated/0/Android/data/org.xbmc.kodi/files/.kodi/userdata/Thumbnails/</from>
<to>/storage/A680-8033/Android/data/org.xbmx.kodi/files/kodi_data/Thumbnails/</to>
</substitute>
</pathsubstitution>
</advancedsettings>
This is the path that shows up when going through the folders on my box using ES Explorer. The 8 x’s are the external Sd cards id. Most of the available info for path substitution as well as my own were written for Android 5 or lower. Has anyone attempted the path substitution since switching to Android 6 Marshmallow and Kodi 17.1? And if so could you pass along what worked for you? Thank you
