Hi Vincent,
Thanks for your reply. However, I've been to both the links you provided before coming here and, because I found nothing there that was remotely connected to the specific issue I've raised - I decided the best thing to do would be to join this community and to post here. There's really very little point in having a forum like this if all you do is signpost new users like me to the main Sony URLs. Besides which, like me, in all probability anyone who ends up here will already have looked at both of those links (Typing 'Sony' into any search engine will lead one to them).
I'm afraid the criticisms made in my last post still stand. My question must be a very simple one for anyone to answer who is knowledgable about Sony Play Memories. According to your own data (https://www.sony.net/SonyInfo/csr_report/employees/info/) Sony employs over 125,000 people. Surely half a dozen of them with expert knowledge about Sony products could be tasked with monitoring your own community forum to help out customers like me - along with others here - who have not had their questions answered satisfactorily. As I said before - this is basic stuff, basic stuff - and so simple to put right!!! Needless to say, I will not be marking your post with "Accept as Solution".
