Hi there! Thanks for reaching out. I understand you're having trouble accessing your "My Account" info on the Family Tree Magazine (FTM) website—after entering the code, the loading circle just keeps spinning. Let me help you with that.

First, just to clarify: is this code part of a two-factor authentication (2FA) process? And is this happening within the Family Tree Magazine website directly in your browser, or inside the Family Tree Maker (FTM) app on your Mac?

Meanwhile, here are a few step-by-step suggestions we can try to solve this:

1. Clear Browser Cache and Cookies: Sometimes, stored data can interfere with login processes. On your Mac with OS X 10.15.7 (Catalina), if you're using Safari:
- Open Safari and click Safari menu > Preferences.
- Go to the Privacy tab and click "Manage Website Data."
- Search for the FTM website (familytreemagazine.com) and remove its data.
- Restart Safari and try logging in again.

2. Check Browser Updates: Make sure your browser is updated. Using an outdated browser can cause compatibility issues.

3. Try a Different Browser: If you currently use Safari, try logging in through Chrome or Firefox to rule out browser-specific issues.

4. Disable Browser Extensions: Sometimes extensions can block scripts or cookies needed for login. Temporarily disable them and try again.

5. Review Two-Factor Authentication: If the login code you're entering is part of two-factor authentication, sometimes it can cause issues with the app or website hanging. Some users have found success by temporarily disabling 2FA on their account (if possible) to test logging in, then re-enable. This is more common with Ancestry account logins paired with FTM apps.

6. Network and Firewall Checks: Ensure your internet connection is stable. Also, any firewall or network security software could block necessary communication. You might want to temporarily disable such software to test.

7. Update FTM App (if app-related): If this is happening in the Family Tree Maker app on your Mac, verify the app is fully updated, as outdated versions can have trouble connecting to servers.

If you’ve already tried some of these or want me to tailor suggestions based on your answers regarding the context, feel free to let me know! Once I know a bit more, I can guide you more precisely.

Are you satisfied with these initial steps, or should we dive deeper?
