Yes!
My TV loses connectivity daily despite following all the instructions on how to set up. Not sure if you are WiFi or Ethernet connected.
Anyway Tech have been looking into my issues, personally I believe there is a software bug issue so hopefully it will be resolved.
However, try:
Change your Sky Glass to the following recommended settings set in Settings>
Set Network standby mode to ON and Overnight power saving to OFF.
Turn wifi OFF under Network if your TV is connected via ethernet.
Once you have made the changes in settings above, do a settings restart straight away on your Sky Glass TV.
This ensures that the options are saved correctly.
Go to Settings>Systems Management>Resets & Updates
Select Restart device
Your Sky Glass TV will perform a reboot. It will take a few minutes to complete
