I can't seem to find any answers here.....
The mouse keeps freezing every few minutes. The Device settings says it is working properly. All bluetooth and mouse drivers are updated. Windows is updated. Metered connection is turned off. Power management button has been un-selected. It seems to only happen when I'm on my cellular/SIM card for data.
It is extremely frustrating as I do a lot of home plan design work and using the finger pad on the keyboard takes FOREVER.
I have exactly the same problem. I reset/restore Windows 10 and tried Windows 10 version 1903 and 1909. The problem persists. I changed the device under warranty-the problem remains.
This only happened after latest May Surface pro X firmware. My Bluetooth headphone(Bose SoundSport wireless) also stutters/disconnects randomly.
