Why does IPsec VPN auto-reconnect fail on mobile devices but not PCs?

[Ok1]

We have IPsec VPN, between iOS and Android mobile users with Capsule VPN. There are also computer versions with this client. There is DHCP in all networks, and judging by the logs, when the IP changes on clients, auto-reconnect fails on mobile devices. Only if you reconnect manually and then it works. However, we don't see this behavior on the PC clients. Auto-reconnection succeeeds when the IP changes. Our users with whom the problem occurs are not traveling, so DHCP is the only factor we can think of that results in IP changes.

Earlier there was a post in CheckMates, where there are similar errors as we have are and PhoneBoy provided an answer that this is normal behavior:

Why, then, don't we see a similar behavior on PC clients?

I presume we are limited by the mobile OS in a way that we aren’t on Windows/MacOS where we can use our own implementation of IPsec VPN and have less restrictions in operating apps in the background.

Is it same behavior on all PCs?
