Hi. I installed dropbox on my desktop and created a dropbox account. I verified the email address. Someone is trying to share a folder with me but I am not receiving the email notification. The shared folder is also not appearing in my dropbox folder. I checked and there are no syncing issues. They tried removing me from the sharing list and adding again but still not appearing in my dropbox and no email notification. I have tried multiple devices as well. How do I solve this?
