I have a family account, and use it across iOS, macOS, and Win10 devices.
I've noticed that updates to logins made on iOS and macOS sync to those devices quickly - nearly instantly. Windows seems to lag noticeably. This isn't minutes, but days, weeks, etc.
Example today - I had added an OTP to a login through either iOS, or macOS (can't remember which), but at least a week or two back, maybe longer. On my Win10 machine trying to log in the OTP isn't there. This is a fresh boot of the machine today, so 1Password is freshly opened, but, not the first time I've used it since boot today. Also, not the first time I've used it since updating this login.
I run into this pretty frequently, and have tried the usual things of restarting 1Password, but generally just fall back to using the web UI view, which is always synced.
Obviously, doesn't help much.
The macOS machines are latest Mojave, and iPhoneX and XS with latest versions.
1Password Version: 7.3.684
