6.3 is the buggiest release they have given us. I don't think it was fully tested before released. Cover issues, Kindle Reader losing formatting when using bookmarks, Sync not working and significant battery drain are just to name some I've come across.
Is there an email address for Fire bugs? There is no way I can type all that in their little app.
I have not experienced a battery drain problem, but everything else needs to be fixed!
