First of all, I am not good at English, so I use the translator to leave a question.
MBP 2019 15inch 10.15.1 The Catalina version is in use.
Magic trackpad 2 in use.
Although the accessability option has checked the option to ignore when connecting the external trackpad.
The other functions are normally ignored.
Problems occur when the palm of the hand is placed on the built-in trackpad
For example, the function of the BTT program is:
The tip tap Left/Right does not work properly.
I don't know if this is my MacBook's fault.
I wonder if it's Catalina or BTT's bug.
Please reply thanks
