I was using Simple IAP plugin fine for months, but suddenly unity IAP turned off, and when I turn it ON it asks for Google Public Key. My game is windows only and I don’t use any google platform. Can I disable this so my purchases return to its original state? Thank you
If you are not using Google, you can/should leave that key blank. It’s not actually used in transactions, it’s only used for reporting in the Dashboard. Even on Google, IAP will work without it.
