I'm able to confirm this issue, however I don't see how we could resolve it, as it is an iOS issue.

Here are the steps I used to test and reproduce the issue:

1. Enable Network Protection and mark my current network as Untrused to connect to VPN
2. Open a different VPN provider (e.g. Passepartout app for OpenVPN) and connect VPN
3. Disconnect other VPN
4. Observe that iOS does not connect IVPN VPN automatically, even though on-demand rules for IVPN are still active
5. When I open the iOS Settings -> VPN, iOS connects IVPN VPN automatically

I would expect iOS to evaluate the active on-demand rules and connect IVPN VPN automatically as soon as there's any network traffic on my device.
