iOS RevenueCat SDK returns Anonymous ID after successful purchase and login(Sandbox)

RevenueCat returns an AnonymousID for originalAppUserId instead of the UUID I send it. After the purchase I login to RC with the UUID(RC returns an anonymous ID). Also, at startup after logging in with the UUID in didFinishLaunchingWithOptions, RC returns the same anon ID in the purchases(_ purchases: Purchases, receivedUpdated customerInfo: CustomerInfo) callback.

This has a material impact on the use of my multi-user app since I depend on the uuid userId to determine many aspects of the app state.

How can I ensure that RC returns the user ID that I gave it?

Here’s how I initialize RC at startup in didFinishLaunchingWithOptions:


let configuration = Configuration.Builder(withAPIKey: "asdf")


          .with(usesStoreKit2IfAvailable: false)


Purchases.configure(with: configuration)

Purchases.shared.logIn( { (customerInfo, created, error) in

                os_log("Purchases.shared.logIn customerInfo: %@", log:, String(describing: customerInfo))

                os_log("Purchases.shared.logIn created: %@", log:, String(describing: created))

                os_log("Purchases.shared.logIn error: %@", log:, String(describing: error))

That could do it. Let us know if you didn’t get this solved. Configuring with a custom App User ID should cause the SDK to return that same ID unless logged out, or login is called again with a different user.

I believe I know what could be wrong. I was calling logOut() in a couple places.
