It's the same with me. Firmware is 1.2.0

I installed this firmware. My X50 Outdoor continues to go offline in the app after a few days. It continues to work in real life. The logged-in devices are displayed as LAN in the main router

@akapal My X50 Outdoor always goes offline after a few days. I have no idea what that is. The reception is good. However, it is only displayed as offline in the app. It works.
