    After purchasing an item the game is frozen. It works perfectly on some devices but not on some others (bug found on samsung J4, J8, S6 Lite). The purchase seems to be done anyway, since when closing and reopening the game the item is there. We don't see any error log neither in the console nor in crashlytics.
    We're using unity 2020 and IAP 4.5.1.

    Hi @BenJuicy,
    Is this behavior only happening on Samsung devices? Did you try other android devices?
    Can you share more details on the tests done and which version of Android is being used?

    This behaviour seems to happen only on samsung devices (not all of them). It has been tested on other android devices without issues. Unfortunately I don't have access to the devices with this issue (it was found by the QA team of a company we work with). But I will ask for the android versions. I did have access to the app they used for the tests but I haven't been able to reproduce the freeze yet.

    Hello,

    Would you be able to ask the QA team to provide the device logs?
    Is there any special manipulation done when doing the purchase that causes a crash?

    We also have this fix coming in IAP 4.5.2 that might solve the issue:

    Hello @Yannick_Denis.

    No special manipulation, they send me videos and it seems they're just clicking the in app button, purchase the item and then it freeze. They sent me this log. The freeze appears near the end of the log.

    Hi @BenJuicy,

    From your logs, I see that the purchase flow is unresolved.

    I also see a bunch of error logs in your ads module, as well as some others, including some null window data. None of those error have to do with IAP, but could be stuck by IAP into a race condition, or be creating a race condition with IAP.

    Either way, I agree with @Yannick_Denis that IAP 4.5.2 should have a fix for situations where we retry indefinitely to get out of a purchase flow deadlock. It should be out shortly. I suggest you check back in a couple of days to see our announcement of it on the forum.

    Otherwise, is it possible for you to investigate to see if your app is trying to throw up another popup and creating a concurrency issue?
