Some regression with mainline kernel 5.9 (during all 5.9 release candidates I've tested as well) - my mouse has to be removed from the previous connections list and re-paired after each time the mouse goes to sleep (waiting a couple of minutes). Working fine with 5.8.x kernels. Ubuntu 20.04, HP travel mouse, Intel AX200 controller (8087:0029) in a Lenovo 14ARE05.
