Reboot didn't work for me, nor did doing a simple reinstall of the app — I had to clean out everything (using AppCleaner). After a fresh re-install and a re-sync all is now working OK again.
Hi all, I've just updated to Mac beta 6.13.1 Beta 1 (455772 Direct) and the app no longer displays any windows. The app launches, the menu bar appears, but there are no windows and most of the menus are greyed out (notably the File and Window menus). I'm kind of stuck. Anyone else seen this, or have any ideas? Thanks, S.
