Hi Alex,
Thank you for your quick response and sorry for the confusion.
Clicking 'Configure AudioMoth' actually worked, thank you!
I thought the previous versions of the app immediately showed a correct time when I clicked 'Local Time' while the device was plugged in, regardless of whether or not the batteries were removed and reinserted before plugging in (, which I am not sure if this is true or not). Then I thought the behaviour of the app changed after the latest update, which confused me. But it seems my mistake!
Thank you for your help! It's all good now.
Ray
