Bluetooth Issues Since Surface Updates - 5 August 2021

I've gotten 36 hours of use of my mouse and keyboard, with 4 hours of continuous use. Sadly, I am now happy if I only have to restart or reattach my BT device every four hours. I used the method described above, which I paraphrase "uninistall both bluetooth AND wifi devices, INCLUDING drivers. Reboot. Make sure your driver is dated 2016. Go into gpedit computer config/administrative templates/windows components/windows update/don't include drivers and enable that so that the next time windows updates it doesn't over-write what you just did."

For those of us angry at Microsoft, I did a little research. They make only about 3% of their revenue from selling NEW Surface 7's (which don't have the Marvell BT chip, btw). They make 0% of their revenue from supporting SP 5's. They don't care. Why should they? I'm just telling everyone I can think of that MS doesn't support their products. Embarassing them won't help, but it may make me feel better.

Very disappointing, I have all MS peripherals for this very reason so when something doesn't work the low level IT workers (who don't even work for MS and are "ambassadors") can't point to the non MS peripherals as the problem.

...and Windows re-installed the crappy drivers again, in spite of the setting in gpedit. This time, however, it was easily rolled back, but still needed a restart.

So I called Tech Support on Friday 20 Aug and they said they are aware of the problem, but they have no answer as to why they are taking that long to resolve the issue. After spending 45 minutes with the person on the other line, I realised I am probably still better off at this juncture troubleshooting on my own. Tech Support didn't even know that after installation, "Firmware updates can’t be uninstalled or reverted to an earlier version" (https://support.microsoft.com/en-us/surface/surface-pro-6-update-history-1c611758-6d57-0a45-047b-ac358460033d). Still asked me to click on the button to roll back on the BT driver version. That much is reflected of their competency.

And .... and.... they were supposed to give me a call back later on Friday cos they couldn't help me after 45min. Guess what? All disappeared without a trace. When I finally managed to find time in between work to call again, "Sorry. Our office is closed for the day".

I've deleted the driver and rolled back to 2016 v15.68.9112.23. Also updated the Win Update under gpedit.msc. Fingers crossed my BT will now work beyond 45min.

Thanks for the update, F1. It's good to, at least, finally know that MS Tech Support are aware of the problem so thank you for getting in touch with them.
