@Denis55 Try new beta version of Deco App 3.8.102 on Android.

@Denis55 Maybe you put your Satellite Deco far away from Main Deco. I also faced this issue with Deco M4 because satellite Deco can't get enough signals to always get online. Try to move it little...

@David-TP This beta firmware of App is working perfectly fine for me better than previous beta firmware.
