D103 G3 issue after grid outage and other concerns

Hello all.  New user here, greetings from Ireland.  I have recently installed D103 G3 Extended version on single phase network with 2 CT's monitoring other circuits in the house.  All was OK and installation was relatively easy and setup OK.

We had during this week, short period of power loss on the grid.  When the power was reinstated, the device failed to reconnect automatically to the WiFi.  Only this evening I had to investigate as there was no data on the dashboard and device was in "Waiting" status, despite my router showing it as an attached device.  However, after waking up WiFi on the D103 and connecting, the WiFi was not connected but my router showed it as attached with correct IP address.  I had to manually reinstate the connection to the router from the device interface.  But the device still would not talk to the server, until I then performed restart of my router, then everything worked normally.

My question is, should the device reconnect to WiFi automatically by itself once grid power is restored and device starts again?

Second issue I note is with dashboard.  How is it possible or is it possible to lock each widget in place?  Sometimes when you scroll on the dashboard from iPhone, it moves the widgets around on top of each other and you have to take care to relocate them back to original position again.  I have tried "Lock Back" function but it does nothing.  Is there some setting to lock the widgets in place on dashboard to prevent unwanted movement?

Thanks!
