Module was compiled with an incompatible version of Kotlin.

Please use the Discussion board if you want to get some help. Please use issues to report bugs.

Description
Documentation states you should add kotlinVersion = "1.6.0"
After updating to 12.10.7 I get Module was compiled with an incompatible version of Kotlin.

Solution
If anyone else is seeing this either update kotlinVersion to 1.8.0 or downgrade lib version to 12.10.5
I'll raise pr to update docs

Updating the kotlinVersion to 1.8.0 I get the following error:

@galenweber not sure about this error, but you can workaround this by downgrading the lib to version 12.10.5 that works with kotlin version 1.6.0

@17Amir17 i have same problem using 12.10.5 version remove the error, and everything work perfctly upto android 12 but in android 13 purchase is not working (products are coming well)it shows "this version of the application is not configured for billing through google play" that error, and if i want to change the kotlin versio 1.8.0 it will conflict other libraries ...what should be the solutions ?
