Trouble logging into AnkiHub

I was able to reproduce the issue on a Windows sandbox and found a working solution. For anyone facing the issue, please try the following steps and let us know whether that works for you:

  1. Open in Microsoft Edge.
  2. Click the lock icon in the address bar then click on “Connection is secure”
  3. Click on the icon to the right
  4. Go to the Details tab and click the Export button
  5. Save the file somewhere (e.g. Downloads or Desktop)
  6. Open the file then click the Install Certificate button.
  7. Accept the default options by clicking Next

  8. After clicking Finish the following message should appear and you should now be able to log in to AnkiHub in the add-on.
