Hi, EdwardWalker5!
Thanks for reaching out to Microsoft Community and posting your concerns. We are sorry to learn about your Surface Earbuds as the left earbud doesn't work after installing the update, as well as not being recognized by other host devices. This isn't the experience that we want you to have. Thanks for noting that taking the time to let us know about this and allowing us to help you out.
Kindly try out the steps below to troubleshoot the issue:
· Place the earbuds back in the charging case for about 20 minutes, then try to reconnect to your laptop via the Surface Audio app.
If that does not resolve the issue, please try to restart the host device (kindly try out your laptop first, then your Samsung devices).
· If the issue is still present, kindly Reset Surface Earbuds.
· Then try to Update Surface Earbuds again.
Let us know how it goes. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.
Kind regards,
Janette_Z
