I can't see customized theme in Android

Due to changes in the Android OS policy, KakaoTalk is unable to load some customized theme lists in [KakaoTalk Settings > Themes].
Each user theme developer needs to update their settings to resolve this issue.

Please share the following with user theme developers.

Go to AndroidManifest.xml file's MainActivity and see if the theme intent-filter has been defined.

The customized theme will be visible in [KakaoTalk Settings > Theme] once this value is added to the customized theme.

Thank you.
