Logitech M350 mouse can not working on iOS 13.4

Hello, I use Logitech pebble M350 mouse to connect to my iPhone,

the device is connected, I try to open Assistive Touch, and It work,

when I connect to my remote computer, It can not wok,

I try to close Assistive Touch, change battery, re-pair my mouse with iPhone,

and the physical mouse still show "connecting...",

even if I close the physical mouse option, This still doesn't work!

Does anyone else has the same problem? or does anyone can solve this?
