Missing "Sync" button

For some reason my Android app is missing the “Sync” button in the history view. Where can I find this? On the iOS app it’s at the bottom of this screen. (The screen doesn’t scroll.)

If RuuviTag is connected all the time to iOS device (connected mode) it’s not possible to connect with another device at the same time. Then button is also missing.

That fixes it, thanks! Slightly unexpected behaviour.

Background scanning on iOS works only in full connected mode and it limits other devices to connect to a same device. Android doesn’t need this kind of connected mode.
