Intune APK Upload Error

Hi, This issue usually happens due to a temporary glitch in the Intune Managed Play Store portal or a problem with the APK’s signing/settings. Since you’ve tried multiple APKs and browsers, it’s likely on Microsoft’s side. You can try: Clearing your browser cache or using an incognito window. Verifying that the APK is properly signed and targets supported API levels. Uploading via PowerShell or Intune Graph API as a workaround. Contacting Microsoft Support since the error has persisted for several days. Most often, the upload works once the portal issue is resolved or after checking the APK.
