+## ⚠️ Caveats
+
+> TL;DR: Only `Testuser` works.
+
+This app uses a dynamic partition value of the current user's ID.
+However, I have not yet gotten this to work with the new Realm `@AsyncOpen`
+property wrapper. To work around this the partition value is hard-coded
+with the value of `Testuser`.
