Inbox is acting funny? I cannot see new emails using laptop/ desktop. It is only visible in my app.

Hi,

I am not sure what to do here.

I was getting a lot of spam and I started sending a lot of emails into junk and I was also blocking senders.

I have totally destroyed my settings. I receive notice that there is nothing in the inbox.

If I go to my APP in the phone - only there I can see new emails.

Has this happened to anyone? How can this be fixed?? Should I delete/ re-install it on laptop/ desktop?
My other email address is mypka@hotmail.com
