Android CaptureScreenshot not working

Been trying to get the Application.CaptureScreenshot(), on Android, for the last few days, and I can not get it to work.

I have a button set up, already made in the Canvas, with a method attached to the OnClick() events in the editor.

 public void ClickScreenshot()
     {
         snapshotStatus = true;
 
     }

Then an IF statement, in the LateUpdate() method will recognize the boolean change:

 void LateUpdate()
     {
         if (snapshotStatus)
         {
             StartCoroutine(CaptureScreen());
             snapshotStatus = false;
         }
     }

Which will go to this IEnumerator method to check if the file exists:

 private IEnumerator CaptureScreen()
     {
         string screenshot = System.DateTime.Now.ToString("yyyyMMddHHmmss") + ".png";
         string filePath = System.IO.Path.Combine(Application.persistentDataPath, screenshot);
         Debug.Log(screenshot);
         Debug.Log(Application.persistentDataPath);
         
 
         // Wait for screen rendering to complete
         Application.CaptureScreenshot(screenshot);
         while (!File.Exists(filePath))
         {
             Debug.Log("Sanky: File exist at location" + filePath);
             yield return 0;
         }
     }

This was from looking at other questions from this site, and I still can not get any screenshots to be made. I do not get any com.projectname.app folder made with any screenshots in the file folder, or anything. Tried using Write Access Internal and External (though this device does not have a SD Card slot).

I originally had just the Application.CaptureScreenshot() in the ClickScreenshot() method, but I am at this point pulling straws for anything. Any suggestions?

By the way, when testing on the PC, the original method above works just fine.
