This seamlessness is also critical for my less-technical family members on my plan. They want the better security, and recognize that a password manager is necessary. But if it was a pain to use they wouldn't put up with it.

I had to Google a workaround (creating a dummy secure note was one workaround) for the times the sync wouldn't work.

I asked why there was no Force Sync button on their support forums, and was told that they took it out because they want their paying customers to report sync issues with an error report instead of giving them an instant fix via the button.

Needless to say, as someone who has been using and paying for 1PW (upgrades and subs) since around 2008, I was not impressed with that response.

To me, the Windows and Android clients seem to be second-class citizens compared to their Apple counterparts.

They don't have a proper Linux client

You can use the pay-one-price license if you already have the motivation to use DropBox.

But on the other hand, for users who have DropBox already—possibly because they aren't using Linux—this does allow them to sync passwords without paying another $40 a year.
