Best way to introduce a cross platform offer code affiliate program?

We are playing with the idea of introducing an affiliate program that revolves around using offer codes to track purchases. Very much in the same way that you see podcasts doing it by telling their listeners to enter code “PODCAST” to get 10% off, which in turn allows the company to track sales and measure campaign performance. I know that iOS and Android both have offer codes, but I think this type of thing would require a more custom solution. Has anyone done this before? I know we could easily build our own system that generates codes, and let users enter a code in the app, which we verify, then display alternate pricing and tag the user with the offer code. But then we have to figure out the best way to track sales, retention, life time value, refunds, etc. to determine how to pay affiliates. Would we be able to utilize any of the integrations for this purpose? Has anyone done this in combination with a promotional service like https://www.talon.one/?Any insight here would be appre

Proper Error Handling

I’m working on the best way to handle errors in my app, referencing the revenuecat error documentation.It seems to me that there are broadly four classes of error:`PurchaseCancelledError` - which is simple enough to handle in the UI `NetworkError` - in which a purchase definitely didn’t go through, and I can give my users a chance to retry the purchase Errors related to my code and configuration - in this case, I should display an error message, send an alert to our error logging system, and not allow the user to proceed. And `StoreProblemError`The last category of error I find puzzling - `StoreProblemError`. The documentation says that “If everything was working while testing, you shouldn't have to do anything to handle this error in production. RevenueCat will automatically retry any purchase failures so no data is lost.” So if I’m reading this correctly, the user will not have an active subscription made immediately, but they will have a subscription made eventually because the rev

There's a problem with your configuration. None of the products registered in the RevenueCat dashboard could be fetched from App Store Connect (or the StoreKit Configuration file if one is being used).

Just launched my app with subscriptions on Monday.On Tuesday I had an iOS user successfully subscribe to a Monthly plan.Now, Wednesday morning, I’m seeing this error in my Sentry dashboard. Not quite sure what to make of this. Clearly things were working well enough ~12 hours prior that someone was able to subscribe - and I haven’t touched/changed anything since.Only the one error / one user so far - but I’m concerned it could continue.

Reading Revenue Cat Purchases Flutter Web

How does RC recommend anyone already using mobile to get the existing purchases and subscriptions for users on a Flutter Web app given no RC Flutter Web SDK. I want to ensure subscribers on Mobile can log in on Web and their subscriptions are retrieved. I see there is the Revenue Cat API, and also Firebase Integrations. I want to understand what the best practice is. Thanks

Ignoring purchase request for already subscribed package error when trying to repurchase a consumable

Hi there,I am using Revenue Cat Paywalls to let my users purchase products. However if a consumable has been purchased before I am getting the error message:Ignoring purchase request for already subscribed packageThis is happening even though the purchase request is for a NON_RENEWING_PURCHASE which is not a subscription.My app is written in Flutter and I am currently testing on Android before moving on to iOS. I have rechecked my product set up on the Google Play Store and they are not set up as subscriptions. These products are not set up with entitlements in RC, they only have offerings attached.Can anyone help resolve this because at the moment my app doesn’t allow the repurchase of consumables which is obviously an issue.

General Questions

Shouldn't customer have access till purchased period though cancelled ?

Let’s consider a scenario where customer subscribed for monthly plan. But after few days, customer cancelled the subscription. Shouldn’t customer be allowed to access to the pro content till the period subscription ends ? Whats the right way of handling such situation ? Do we refund and immediately close the subscription or whats the best we do when user cancels the subscription ?

How to show annual subscription price per month?

Sorry if it was asked before, I searched but couldn’t find anything :(What is the best way to calculate the price for annual subscription per month/week? I want to show user, how much he/she will pay for an annual subscription each month or week.An app already implementing this, is Snapchat. I checked all over revenuecat documentation but didn’t find this feature.
