Firmware update

I just bought a Shelly Plug and of course wanted to firmware update. I can switch it on off both from app and web and it seems i Can manage the other settings but not upgrade. It reports firmware 20171124-082532/???, i can do upgrade firmware and it restarts fine but after restarting it reports the same firmware. I doesn't differ if I do this from app or web interface. Same result. I died to reboot, and factory reset but nothing helps.

What to do? Thanks?

Thanks! Tried that with 1.5 and 1.6 and copied the URL received from the page including my IP adress to the Shelly Plug V2 (white). I get a blank web page with the text
{"status":"scheduled"}
but nothing happens with the Plug sa I can see. What am I doing wrong?

I also now tried with 1.7 firmware version and it stills say the same on the web page but the Plug WiFi lamp went from blue to red and is still red after 5 minutes. What does that mean?

#66er any more ideas for this?
