I have multiple vaults configured for syncing via Dropbox.
On the Mac, any 1P changes are immediately pushed to Dropbox.
On my iPhone, those changes are not shown until I manually run a Sync Now from the Settings>Sync screen.
For example, in another thread I was discussing adding custom icons to some entries. After updating the icons and saving them, I opened 1P on my phone to see how they looked but they were not updated. I did a manual sync for the primary vault and the changes appeared.
My other vaults, which also have been updated tonight with icons and a bunch of other cleanup, have yet to automatically update. In the Sync details screen for each vault, the Last Sync is yesterday.
Wouldn't it be ideal if it attempted a sync any time I launched 1P and logged in?
Is it possible to use the background app refresh mode to sync often, even if I haven't launched 1P?
P.S. While writing up this post, I had 1P open to the sync screen. I switched to the phone settings to get the iOS version number. When I opened 1P again, it came back to the sync screen and I briefly saw the "Dropbox >" text switch to "Syncing" and then right back. However, looking at the details screen, they still say last sync was yesterday. This is not a Dropbox login problem because if I hit Sync Now, it immediately updates the vault.
