Magic Mouse functions don't work on MBP when waking from sleep w/ external monitor

2017 15" MBP (2.9GHZ Core i7, 16GB RAM, 512GB SSD) running Mac OS Catalina 10.15.6
Magic Mouse
32" 4K Samsung monitor (connected via Anker USB C hub and HDMI cable)
BTT version 3.401

Sometimes when I wake my laptop from sleep when connected to the external monitor, BTT Magic Mouse functions do not work. Cannot intentionally replicate the issue -- happens randomly.

Quitting/restarting BTT does not resolve issue. I have to restart my computer to get BTT to function properly with the Magic Mouse again.


Same situation for me. Also, during work ex. middle click stop working occasionally.

Would love to know if there has been any progress on this. Problem still persists :frowning:

Thank you!
