I have a problem with resetting the main unit. The lost wifi connection can’t be repaired because on resetting the device there is no sound confirmation from the remote controller. Everything else works normally. A problem occurred after installing the new software version 1.10.2.24. Reinstalling the older software versions doesn’t help.
Thank you.
