FMI has always shown my current devices, however I just signed on to deactivate my 5s (which had the standard remove option) and noticed my old iMac and Mac Mini are still on there. I sold these years ago and they have not shown up before. I can erase them but feel that would be harsh on whomever bought them from me via eBay, there is no 'remove' option which is the bigger issue. Has anybody else encountered this problem?
