VPN for iPhone XR

After switching to Apple from Samsung and using NordVPN on both I have noticed this small difference. When I used my VPN on my Samsung it displayed a small key icon on the top left or right, signifying the VPN is on. Now when I enable a VPN on my iPhone it only pops up a “VPN” icon for a moment to cover the battery and wifi icon, then goes away.

I know this is a small change but did Apple mean it to work this way? And if not is there a way for it to become a permanent icon while enabled like it did on my Samsung?

Yes, it saves your battery, But if you still want to saw this then you need to swipe down and you can control it, you can see the icon of VPN you’re using at the top.
