When I use Chrome Inspect tool I get the following error in the console.
'AudioListener.dopplerFactor' is deprecated and will be removed in M55, around November 2016. It has no effect as the Web Audio doppler effects have already been removed internally. See https://www.chromestatus.com/features/5238926818148352 for more details.
c2runtime.js:3215 'CanvasRenderingContext2D.webkitImageSmoothingEnabled' is deprecated. Please use 'CanvasRenderingContext2D.imageSmoothingEnabled' instead.
Could This be causing the problem with Facebook Login?
If so, any idea on how to fix?
