Wind display have stopped working lately

I have had wind working fine in my Z82 as long as I have started the Garmin app, made sure I was logged in and ensured that app and range finder were connected. And it continued to work if I changed app or the phone locked.

Now, as soon as the Garmin app goes out of focus (switching app or, usually, the phone locks) the wind just becomes an exclamation mark in the display on the Z82 Disappointed
