Just looking to get some thoughts on what might be happening here.
We have devices that were picked up by our e-recycler in 7/22. They send us a list of serial numbers they have and we then take them out of JAMF. However, a handful have updated inventory post recycling. Other than the company manually connecting them to a network, any other explanation?
Did you make sure to wipe the devices and release them in Apple Business/School Manager before handing them over?
I would suggest deleting the JAMF Inventory record when you dispose of a device. There is no way to automate deleting the record (API withstanding), and you pay per device for JAMF.
