Mouse pointer absent when running windows 10 after upgrade of parallels 16

Hi,
My apologies if this issue is in another recent thread. I am having problems now with my trackpad mouse pointer on my MacBook running Catalina 10.15.7 in windows 10 since upgrading to parallels 16. I have tried one or two options advised re similar problems on these forums from 2019 but nothing is resolving the problem. The pointer simply disappears when held over the windows vm screen. I have tried configuring the mouse settings etc so can anyone advise on how to solve the problem please. Any advice gratefully received!

 

Hi, did you try this?
