Recent Smart gas Meter Install is blank

Hi All, Just over 3 weeks ago we had gas and Electric smart meters installed. Just went out to look at the Gas meter as i noticed that it wasn’t updating on the app and the screen is completely blank,

Any ideas if this is a problem

Hi, the screen on the gas meter turns of to save energy. Press the “A” or “B” buttons to turn on the meters screen to get readings. I have no idea with the app not updating, and bulb will have to look into that.
