Android widget for Victron Connect not working?

Hello there,

does anybody use the ANDROID widget (not the VRM one) for Victron Connect? Goal = use a standard tablet (like my Samsung one, for plenty of other usefull stuffs) as a wireless Ekrano.
Documentation here: 14. Android widgets
On my tablet and phone I got a message when dragging the widget template to the screen: “Select a device Device not found”. (screenshot included)
And that’s it, except that Victron Connect shows 1 local (Cerbo GX) and 2 distant VRM installations.
Tried with v6.31 and 6.32 (last update, today), but nothing.
Did/does it work for you? What’s my pbl then?

Thanks in advance
Chris
