AUTH_TOKEN_VERIFICATION_FAILURE (Amazon Appstore DevTest for IAP)

[tvonos]

Hi @Super_Mario

Just on the off chance, might be worth taking a look at the following post:

Error on startup for IAP Billing Client

Thank you @Levon for your assistance. I now have it working! (recording here in case anyone else hits this issue) Going through all the documentation the solution I found was not obvious. (well not to me) The key to get it working for me was to update the proguard-rules.pro file to include: -dontobfuscate in addition to the data specified here: It is mentioned in the next section in that document - but not as a required change.

It was the obfuscation that caught me out.
