Integrar MercadoPago

Estoy tratando de integrar MercadoPago a mi app pero siempre sucede lo mismo:

Failed to resolve: com.mercadopago.android.px:checkout:4.86.0

Error mostrado:

Failed to resolve: com.mercadopago.android.px:checkout:4.86.0

Build.gradle:

implementation 'com.mercadopago.android.px:checkout:4.86.0'

¿Alguien sabe que hago mal?

Actualización:

El minSDK que utilizo es el 26.

android {    compileSdkVersion 30    defaultConfig {        applicationId "com.frabasoft.mitaller"        minSdkVersion 26        targetSdkVersion 30        versionCode 1        versionName "1.0"        multiDexEnabled true        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'        }    }    compileOptions {        sourceCompatibility JavaVersion.VERSION_1_8        targetCompatibility JavaVersion.VERSION_1_8    }    buildFeatures {        viewBinding true    }}

El build.gradle:

buildscript {    repositories {        google()        mavenCentral()        maven{            url "https://plugins.gradle.org/m2/"        }    }    dependencies {        classpath 'com.android.tools.build:gradle:7.0.0'        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }}allprojects {    repositories {        google()        mavenCentral()        maven { url 'https://jitpack.io'}    }}
