Eco Mode is shutting down when router reboots

Hi everyone.

Please, sorry for my poor english

I have 4 Shelly Plus (2x Plus 1 + 2x Plus 1PM), FW 0.10.3. in a wifi network of a Technicolor router., and all 4 goes out of eco mode every time I reboot the router (or every time the router reboots itself), and then the eco mode stays off until I reboot every single relay. In this screenshot, the router rebooted it self at 04:10, I rebooted the relays at about 09:20, then I rebooted the router at 10:00, and then I rebooted the relays at 10:15.

I also have another 2 shelly Plus1, in a different wifi network of a Tp-Link router, and also these 2 shellies behave the same way.

I've tried every old firmware, and also the 0.11 beta with always the same behavior

What can I do to resolve this problem?

Yes I think the same thing.

And I think also that it is a firmware bug

Is there here someone of Allterco that can look into this?
