I also just looked into NFC and I had similar observations as @trezm. I configured a NFC url, which worked fine the first time, but then even after closing my android devices browser or using a totally different device, it did not work any more. What works is taking out the battery and configuring the url again.
I assume the NRF.nfcURL() is not one-shot, eg. it does not clear itself after it has been used. I have the latest firmware 1.91 btw.
