So, I tried everything :
-
Apk is uploaded properly
-
Already waited for 4 hrs now

-
Tested my in app purchase, everything worked except that the transaction callback always in failed state saying invalid client.
*scratching my head here, since I’ve done this before in earlier version. Now both my managed and unmanaged item won’t work.
This is scary since I can’t make sure if I want to update my game everything will run again.
How long should I wait? Is there an easy way to tell what’s wrong with the InvalidClient message?
Thanks
