Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. Can you please tell me HOW you access your Yahoo email account? Is it using a web browser like Internet Explorer or Chrome? Or are you using an email program like MS Outlook 2016 or the Mail app in Windows 10?
Please let me know by replying to me here so that I can help you further.
