im developing an app in react native, but i have some problem in deploying to Play Store. I already generating an upload key using keytool as the react native's documentation said, and i got a file named <my-upload-key>.keystore. Im done with editting build.gradle and gradle.properties to configure my upload key.
My problem is what should i choose with these options, should i choose "Let Google create and manage my app signing key (recommended)" OR "Export and upload a key and certificate"??
Once i choosed the "Let Google create and manage my app signing key", then my app successfuly uploaded and published in playstore, but when i download it from play store, my app wont open and only show white blank screen. My app running well when im using generated APK from react native.
If i choose Export and upload a key and certificate, they want the file uploaded as zip file containing the PEM file.
Am i miss a step in uploading the app to Play Console?
