Pi Zero, Wifi Dongle Support Removal?

01.07.2018 build supports my Wifi Dongle (Netis WF2120, 2.4Ghz) for my Pi Zero when updating to 01.01.2020 the dongle ceases to be recognised. im currently building older builds in order to see when the functionality was removed. Can anyone advise if the functionality for this particular adapter was removed or if it just a ‘quirk’?

Support for some Realtek based dongles was removed with the November Update.

July '19 Build Installed, Auto Updates turned off. thx for the info
