i no longer have an app that reads mobi files...10 months blocked from all mobi files. 10-12-19 Amazon won't allow remaining library to be accessed from a new galaxy 9 phone. It must be there first then a complex process done on the imaginary file deleting all books I've bought. Then presumably i will be allowed an empty kindle download? Right! UPDATE Now the app will not sync nor track my location nor remove f4om library nor delete content nor adjust view to see.
