Hello @Joanne882, I hope everything is well with you.
Have there been any updates since you posted in our community? Have you reached out to the support team for their advice on this?
I suggest following these basic troubleshooting steps to see if resetting the settings helps:
- Log out.
- Close all browser windows and tabs.
- Open a new window or tab.
- Clear your cache, cookies, and browsing history.
- If you're using an app, delete and reinstall it.
- Log back in using EMAILFROM_ACCOUNT.
Keep us posted.
