M24LR NDEF not recognised by Windows Phone 8?

I've tried a number of ways to get M24LR tags recognised by a Windows Phone 8 device (Lumia 920) - but to no avail.  WP8 is supposed to recognise NDEF formatted tags but doesn't.  I've tried formatting with the STM NDEF tool and using a borrowed Android phone to use the suggested app - the tags are recognised in Android and yet not in WP8.

Any suggestions?    Is there something low level I need to set or program apart from just telling the STM software to format and encode (in my case a simple plain-text) an NDEF?    Or is there some manufacturer ID/protocol setting in addition to the format as NDEF that I need to make sure is set to get compatibility?    WP8 will not permit low level format but will allow write/read with other brands of "compatible" NDEF tags...

Any advice greatly appreciated - love the energy harvesting feature which is why I want to use STM M24LR tags rather those from another vendor...
