After few updates, several global reset, my E5 with Iphone 16pro with Ios26.0.1, stll have following mobile app behavior.
The problem looks like more connected to mobile app reconnecting process, while BT with iphone works properly.
Mobile app disconnecting all time watch is far away from phone, and when they come together, watch and phone reconnect and watch gets notification while mobile app still disconnected. Only killing mobile app and booting up again will make mobile app to reconnect.
Do you experience same situation?
