I have had huge issues with the Mac OS version of 1P not syncing with my iOS version.
Very frustrating as I save a password on my phone, and it isn't updated on desktop, and then I have also experienced passwords being overwritten by desktop app when I saved a more recent version on my phone.
Sync on phone is set to Dropbox, Sync on desktop I can't even see in Preferences! Following support article in documentation BUT my preferences don't have a Sync tab?!?!?!!
Would appreciate any help!
