Logitec MX Master 2S disconnect.md

I am using a Logitech MX Master 2S mouse since a while. In recent weeks/months, I see occasional disconnection issues.

Question:

It is unclear whether this is a mouse or a Windows 10 update issue. How can I diagnose this further?

Observations when things go wrong

• Using mouse without any problem
• Suddenly, mouse cursor no longer moves when moving the mouse.
• Light of active profile (2) blinks.
• Device is still connected according to Windows

Workaround

• Add the mouse again as a bluetooth device in Windows 10.

OR

• Turn airplane mode on/off in Windows AND turn mouse off/on

Frequency

History

• Asked Logitech for help https://twitter.com/jawndotnet/status/1198914083380178944
• Then opened Logitech ticket https://support.logi.com/hc/nl-be/requests/1947798
• Reported issue on Microsoft Feedback Hub https://aka.ms/AA6o8h7

So after more than a year working smoothly using Bluetooth (once it had a small hiccup but it was resolved quickly), I am having trouble with it. I needed to change the BT card in my old Macbook pro mid-2012 13" because it was having erratic connection when >2 BT devices are connected.

All seemed fine after I replaced the BT card; I could quickly reconnect my Logitech keyboard K380 and a BT speaker, but for almost an hour I was trying to reconnect my mouse with no luck. This mouse is detectable on my Android phone, so there's no power problem here.

I've followed the guide here: https://support.logi.com/hc/en-us/articles/360023195654-Resolve-Bluetooth-Wireless-issues-on-Mac-OS-X
Still, nothing changes.

Then I try the dongle and it works! However, having used the BT way for so long, I am very curious as to why it just don't want to work anymore.
