On my Vivoactive 3 - probably since/with SW - version 8.20 .
the display is greyed out / dark during training.
The brightness is set to 100%.
The watch is as bright as ever,
The display fades, is grey.
Only when I start a training session, the display suddenly becomes dark (grey).
It is so dark that I can no longer read the display during an evening workout :-(
How can I fix this?
