Welcome to the Forums, and thanks for posting! Quick answer: at the moment, the Appstore SDK Plugin for Unity (and specifically its libAmazonIapV2Bridge.so) is 32-bit only, which means that you would need to build and submit your game/app as a 32-bit binary.
If, however, you require your game to be 64-bit, then I would suggest to use Unity’s IAP directly, please see:
Oh, but that basically means that using the official SDK makes the app incompatible with the latest Amazon devices (such as Fire tablets 2021 and later), quite a strange situation. It would be good if the documentation specified that it is better to use Unity IAP, this would save developers a lot of time.
Hi @Levon, I just realized that Unity’s IAP version 5 unfortunately no longer supports Amazon, and as others have mentioned, it leaves me stuck on version 4.x.x until I can implement Amazon’s Appstore SDK Plugin for Unity. If 64-bit isn’t currently supported, does your team have a timeline for when the next version will be available? Thanks.
Thanks for posting. This issue is with the relevant team. I have communicated the importance of this to them, however I do not have an ETA of when 64-bit is going to be supported. Thanks!
