Transfer files to your android/Fire devices using any web browser. Amazon Appstore version supports transfers to both Internal Storage, External Storage, A limited replica is available on Google Play that uses Storage Access Framework and requires no permission but can only send to Downloads folder.
Hey, Are you not able to find udpates for the app, is that the issue?
If yes, then could you tell me whether you're using the Google play or amazon appstore or github version of the app??
