Hi, Dejan,

Thanks for your response.
I guess it's more a bad feature of BigSur, not a problem with Hansa.
As far as I read, there are problems with this "invisible ink" even in Word or Outlook.

As I said, I can't actually update the customer right now.

Also, I suppose that not every HansaWorld customer is using the lastest version on macOS and I hoped that there is a solution for that problem with the new OS...

Best regards,
Flaviana
