External Hard Disk Failed to Mount on macOS Sierra

Hi guys,

I've just upgraded my iMac to macOS Sierra this morning. I've got my external hard drive formatted NTFS using Tuxera NTFS. I've updated Tuxera and restarted the machine. However, I don't see the external hard drive mounted on Finder or Desktop as usual but I can see it on Disk Utility.

Does anyone experience the same or know how to fix this? Please help.

Thanks.
