Can I successfully call SKStoreReviewController.requestReview () if the user has already rated my app?

I would like to invite my users to rate the iOS app. I couldn't figure out if a tooltip would be displayed in the app if a user has already rated my app (either in the App Store or in an in-app view invitation) - does anyone know?

Additionally, in this documentation, Apple suggests that we allow a week or two between in-app view request attempts. Is this a hard cap set at the OS level that will prevent requests to view apps from appearing, or just a guide?
