This add-on makes updating Anki decks smoother. Please use it only if you have a very old version of the deck and are experiencing difficulties with updating it. By default it is easier without this add-on.
Open Anki > Tools > Add-ons
You can check page of Add-on “special fields”
Click Get Add-ons > 1102281552 > OK
restart Anki
open settings of Add-on special fields Tools > Special Fields
click ‘Update’ Settings
also, if you like to protect fields which you edit yourself, like native or marks - you may add them, and Add-on will protect them while next update.
For more details how to use this add-on see small video.
Now you can update your decks.
