This is a temporary fix.
It is the same as the Special Fields addon featured in AnkingMed, but it is skipping over the section that is causing an error I don’t know the cause of, as it is affecting some people but not others Anki versions.
It is still working properly ! However if you do wish to have your import message pop up after a successful import, what you will have to do is delete this addon file, and download the proper Special Fields addon.
I will take this addon down when all the problems have resolved, and post an update on the Special Fields Addon page.
Until then, apologies of any problems that have arisen, I will be fixing them ASAP.
