I think with any install of BitWarden, be it a browser add-in or separate app, the one you are adding a new credential into knows enough to sync to the cloud, but the others won’t know that new data awaits in the cloud until they do a scheduled query/poll or you manually sync through those clients.
Having a push feature only works if you can engineer your app or add-in to open up the necessary ports or tunnels in the OS itself. Polling on the client end will always be easier to implement.
Also: just checked BitWarden v2.8.0 (449) on iOS 14.4, no setting for “swipe to refresh” anywhere in its settings.
Absolutely. I don't know what eventually triggers the vault on my iOS device to update. It definitely isn't a push notification when the vault is modified on other devices. Probably just a simple duration-since-last-update timer, like the Chrome extension.
My trouble was specifically related to the 'Pull down to refresh' behavior being disabled by default though. If that feature is disabled the new items will appear sometime, with no way of knowing when that will be. I honestly don't even know why that feature has an ON/OFF switch, it should just be permanently enabled.
