Purchases.purchasePackage hangs in the try block or goes directly into the finally block without resolving/rejecting the promise

Describe the bug
I encountered an issue with the subscription process. Initially, I purchased a subscription and subsequently canceled it. After a few minutes, I attempted to repurchase the subscription, having confirmed through the webhook that the CANCELLATION event had been triggered. The Apple subscription process proceeded as expected, and I received an alert indicating that the purchase was successful. However, the function call Purchases.purchasePackage, which is expected to either resolve or reject the promise, appears to hang instead.

When a finally block is included, the execution proceeds to that block, but the expected resolution or rejection of the promise does not occur. Additionally, if I comment out the finally block, the line log('json', purchaseResponse)) is never executed, indicating that the function is stalling at this point.

This behavior suggests that something is preventing the function from properly resolving or rejecting the promise after the purchase process.

Additional context

const onPressSubscribe = async () => {
    try {

       log('notify', 'Product ID: ' + product_id)
        setLoading(true)

        const offer = offerings.find(
          (item) => item.product.identifier == product_id
        )
        const { customerInfo } = await Purchases.logIn(user_id)

        // after this function call it goes to finally block when I deal with apple subscription process
        const purchaseResponse = await Purchases.purchasePackage(offer)

        log('json', purchaseResponse)
        log('success', 'Subscription Purchased Successfully')
       
       // perform stuff to update user data
   
        setLoading(false)
      
    } catch (ex) {

        console.log('Error', e.message)
        setLoading(false)

    } finally {

        // Here I am trying to see if the customer info is updated but it return a json showing that
        // there is no subscription purchased
        console.log('Finally')
        const customerInfo = await Purchases.getCustomerInfo()
        console.log('customerInfo', customerInfo)
        setLoading(false)
    }
  }

@bilal1031 Do you get the logs from right before purchasePackage but not the ones after? Is it possible that offer is null or undefined, causing an exception at purchasePackage?
And also, are you able to get the debug logs when you run that code?

In my case, when I execute Purchases.purchasePackage, the native iOS payment system opens, and the whole process finishes with 'Ok', but it doesn't return control back to my app. Instead, the native iOS payment system reappears. On Android, it works perfectly. I'm using the same versions of the libraries as @bilal1031

Yes, I get the logs from right before purchasePackage but not the ones after. I also reviewed the code and confirmed that the offer variable is never null or undefined, as the function throws an error in those cases. I also tested by passing a hardcoded package as a parameter. Additionally, the scenario described by @crico, is the exact behavior occurring on iOS and it aligns with what I'm experiencing. I am not able to get the debug logs as I am using the expo development-build on a physical device.

any news?

Uhm, is anyone at RevenueCat aware that this issue is a real blocker for adoption? In our case, most of the time, the native purchase UI does not even appear. The call to purchasePackage just hangs. No UI appears, no promise rejection, nothing.
