Hmm, I can log in using Google. If you’re willing to do some debugging here are some instructions:
- Open AnkiPro in your browser
- Right-click anywhere on the page to open the context menu and click the Inspect option (might have a slightly different name in your browser, but that’s the name used in Chrome and Firefox at least).
- Go to the Storage tab (Firefox), or Application (Chrome)
- In the sidebar, expand the Cookies item and click on ankipro.net
- Send a screenshot of the values to the right. The add-on relies on the
AnkiProToken
value. Maybe it’s missing for you for some reason.
