Upgrading to IAP SDK V21 from Unity

Updating library files to support Android OS from v19

However, if only the library files are replaced, new functions provided in IAP SDK v2, such as multiple purchases and subscriptions, may be unavailable.

Delete the v19 library files.

Remove GameObject

Remove the GaaIapCallbackManager GameObject. In Unity Plugin with v21 applied, you no longer need to manually add GameObjects. If you have done all of the above, you are ready to apply the IAP SDK v21. Now, you can apply by referring to the guide for Using ONE store IAP from Unity.
