Iphone + Raspberry Pi 4 Over movile hotspot

Tailscale installed on both devices, granted both devices with a tailscale Ip, can ssh/ping/vnc when on same network as usual, as soon as I migrate the Pi to my iphone hotspot, which is internet access for both devices, I cant ssh/ping anymore, which I thought was tailscales intended purpose, what am I missing?

Do you have another device on your tailnet that you’re trying to access the pi from, or are you accessing it from your phone?

Ive outsourced currently to dragging my laptop around, but yes I was attempting to connect via my iphone 11 running tailscale> Hotspot> Pi with tailscale server= same “network”?? so I expected a connection but Im definitely overlooking something
