Hi @DavidWilliams7,
The first thing that comes to mind if a survey is published and working fine but doesn't appear in Connect is that you don't own it (has anyone changed the ownership on it?) and that the survey folder is not on your local drive.
Can you see both old and new survey folders in your My Survey Design folder (usually under C:\Users\your_username\ArcGIS\My Survey Designs)?
If you do see both folder, try to hit the refresh button on Connect (top right) or shut it down and restart. Make sure the folders have all the relevant files in it (survey.xlsx etc). Another thing you can do is change the folder name, and restart/refresh Connect - sometime it takes it a bit to register name changes.
If you can't see the old folder on your local drive then somehow you deleted it. If you own the survey and it is published but it's not on your local drive you should actually see it in Connect with a Download option (assuming you're connected to your organization). Otherwise I'm not sure what it could be.
