Can't get Promotional Offers to work

I have followed instructions from the official documentation (https://docs.revenuecat.com/docs/ios-subscription-offers) but I can’t get promotional offers to appear.

I’m using a sandbox user, which has an expired annual subscription. When I call any of these methods, I either get 0 offers or it says that the user is not eligible for the promo offer (pay up front, x% off first year).

let d = package.storeProduct.discounts (returns 0)

let e = await Purchases.shared.checkTrialOrIntroDiscountEligibility(product: package.storeProduct) (returns ineligible)

let promoOffers = await package.storeProduct.getEligiblePromotionalOffers() (returns 0)

Here are the entitlements for the user:

identifier=pro,

isActive=false,

willRenew=false,

periodType=Normal,

latestPurchaseDate=Optional(2022-05-28 12:36:19 +0000),

originalPurchaseDate=Optional(2022-05-27 16:03:13 +0000),

expirationDate=Optional(2022-05-28 13:36:19 +0000),

store=Store(rawValue: 0),

productIdentifier=com.mycompany.myapp.pro.yearly,

isSandbox=true,

unsubscribeDetectedAt=Optional(2022-05-28 12:36:07 +0000),

billingIssueDetectedAt=nil,

ownershipType=PurchaseOwnershipType(rawValue: 0)

What I am doing wrong?
