Are you guys seeing the physical web advertisement from RuuviWeather in the iOS Chrome widget with the latest version of Chrome ( 62.0.3202.60 ) they just released on 18th October 2017?
It does not work for me. The only clue that I found is: https://github.com/google/physical-web/issues/931
What do you guys think? What other alternatives can we use to read the sensor data on iOS?
