I'm not able to transfer images and videos from the Sony α6000 to my smartphone via NFC or wifi. It's just says 'sending cancelled' on the camera and 'unable to connect' on the smartphone. Please advise. I have used the above to successfully transfer images before.
I have noticed that NFC isn't always working to well for me either (Sony A77II).
Try opening the app and manually configuring the wifi connection.
After this opening the app using NFC or just opening the app manually will give an instant working connection regardless of any planet alignments.
