Interesting! Could you please send a screenshot to contact@tinkerstellar.com? The app does rely on web content for some parts of the interface, but those web resources are loaded locally from device itself, without reaching anywhere outside. Do you have any local proxy configured on your device, or perhaps some restrictions (Screen Time or other) configured?
