Thanks for sorting this. I know if was years ago but I had such problems with stuff not working in 2019 I reverted to 2018 until Jan this year. We have learned to always run software a year behind so most bugs can be resolved. Just now start on VW2020 and this fixed a major annoyance.
(Also, could VW not have chosen a different colour for the taskbar logo? We had black last year too!)
