Folks, I have a 75UH8500 and an 65UH8500. and both are on the latest firmware 4.30.19. I can't get the Amazon app to launch or update. When I try to update. I get the error message: Not enough storage. Delete unnecessary files and try again. I have plenty of space. The update is 87MB and I have over 422MB free. Does anyone have any thoughts? Thanks,
