Bug: latest 4.46 update broke venu 2s display

Hello

This morning I woke up and my venu 2s displayed the message that the software was updated to 4.46.0.24.  After that the display doesn’t show when I raise my pulse. It doesn’t switch on either when I do double tapping. It only switches on if I press the lower button on the watch. 

What should I do to fix this?

Thanks

Sandra
