Limited users, switches disappear on the app

[Andrex]

I've got this strange behavior:
if I setup the Android app (Domoticz or Dromotica) with an admin user, everything is fine. If I set it up with a limited user, everything is fine for the first hours/day, then in the app everything disappear, no more switches, utilities, etc. all empty.
I've tried to update to the latest beta (V3.8153), but the problem persist.
Where could be the problem?
Thanks,
Andrea
