I have had anki for a while and every time I try and add an addon it says my account is too new, I have been using my account for over 3 months. Do I just need to keep waiting? I was trying to add the anki remote one, the spell check one, and the symbols one.
You don’t need to wait at all to use any of the shared add-ons. You just need to copy and paste the add-on ID into your desktop app.
The new account restriction is only for uploading add-ons that you made to share them through AnkiWeb.
To install add-on on your on system: Add-ons - Anki Manual.
