Manage Licenses fails to remove devices

If you really do need a license removed, ask Norton support to remove it, that should work. (if they co-operate...)

Yes, I think "Norton support, can you just remove the license association for me" is where they end up running into some kind of document that directs them to say "you must contact Amazon."

I've been assuming it's just a misunderstanding or mistaken search match for them, confusing the "Amazon-purchased entitlement to the Norton 360 subscription itself" (which yes, I would need to talk to Amazon if I had a concern with this) with the management of individual device licenses within that Norton 360 subscription (which is 100% Norton's concern, to my knowledge).

But I've tried three times on three separate Norton support cases, and cannot get them to recognize that this is a functionality issue with my.norton.com itself.  They claim being unable to manage anything about my account, because "it was third-party."  It might even be true that the Norton support agents are blocked from taking some action they would normally take; but it's still a problem that needs escalated within Norton support, not Amazon.

So if a Norton support agent can remove the license associations I need to remove, I have not yet run into the Norton support agent willing to actually do that.

think for my as test: I started with View Devices > Manage License 

Understood.  I've "seen" that option, although it seems as though it's not supposed to exist for me.  The first time I enter the my.norton.com page, the "Manage Licenses" option in the drop-down under View Devices MAY be shown to me.  Or it may not be shown, and "View Devices" and "Download" are the only two options in the drop-down.  If I refresh the page, or go to another account page and come back to this page, "Manage Licenses" will definitely NOT be offered in the drop-down.

But it's a moot point, because even when "Manage Licenses" IS offered in the drop-down, selecting "Manage Licenses" from that drop-down simply ends up taking me to the "download to this device, or download to another device" page.  It does not take me to any kind of license management capability, nor to the page you're successfully accessing and showing in your screen shots when using this method.

In your screen shots where you used the same "Method 2" that I am using, I get the "Remove License [Cancel] [Remove]" prompt you're showing.  But upon confirming "Remove", that's when I see the web interface has made a https://webapps.norton.com/api/devices/deleteDeviceBySeatId request which receives an HTTP 500 (internal server error) response, and simply "nothing happens".  Meaning the confirmation prompt goes away, but the device is still in the license list.

It's feeling like the my.norton.com interface or back-end got updated in a way where now certain product SKUs simply aren't handled successfully or as expected.  Even though they used to be handled successfully.  I'm just guessing, but it was sometime in 2022 when I last successfully removed a device from the "Manage Licenses" list using Method 2 on this same Amazon-based subscription.

I suppose it's possible that "any device assigned a license after a certain date" is what's failing to be removed.  Meaning the last one I successfully removed may have been successful not because of "when" I removed it, but because of when the device had been originally installed.  From my obfuscated screen shot earlier, the devices with install dates "11/16/2020" and "6/14/2023" are two I have tried to remove which fail.  Not shown in my screen shot, further up the license list, there is also one from "9/5/2023" which fails to remove.
