I did get an acknowledgement from Strathclyde at the end of October (after a fairly early submission for primary), but my gmail sorted into spam! Perhaps the same thing has happened to other people. Worth checking the spam folder in case. I only noticed it recently and had been wondering why they hadn't sent anything. I applied for Strathclyde, Dundee, Edinburgh, Glasgow, and UWS. I've received an invitation to interview at the UWS and only acknowledgements/requests to create accounts from everyone else.
