Can't find my Spark projects in Adobe Express when logged into Adobe account

[Lori33017647wph3]

I created the following projects in Adobe Spark in 2016:

https://express.adobe.com/page/YpBbk/

https://express.adobe.com/page/0kzb1enO2ETNg/

https://express.adobe.com/page/NNhvPv5Q9vaiy/

https://express.adobe.com/page/hPXmcxIUO6wYh/

All of the projects are still live with a new Adobe Express URL. I have tried logging in various ways under both my Adobe accounts, but so far, there are no project files stored in either account in Adobe Express. How do I edit these projects/access my content? Surely, someone working for Adobe can answer this. It seems to be a common issue still without resolution.
