Pokémon go plus keeps disconnecting

Is it just me or does Pokémon go plus keep disconnecting after like 2 minutes. When I try to reconnect, it often doesn’t and I have to restart the app to connect (sometimes it doesn’t work but normally it does). Anybody else having this problem?

Oh I almost forgot… Go+ just disconnects every time I switch to Ingress or lock my screen. iPhone 6 iOS 11
