Demo server account is not visible with the owner's apk
Seriously? Traccar Manager is the official app.
WONDERFUL ... works very well. Thank you
Yeah it seems Demo3 did a rebuild/cleanout. If you were using demo3 you will need to reload your trackers. It's a risk with demo servers as they are freely hosted by kind souls on their servers for us small guys to use. Ive done it twice with demo3 now. Expect it every few months. If you want reliable you need to host one on your own server or pay Traccar for a plan.
Really there are not an official apk for to tracks gps devices under demo servers
