I’m not sure if this is the right place to post this question, I’m new here.
I logged into Dropbox from my phone earlier today to find a folder to share with a friend and discovered a random video file in my recent activity saying it was accessed yesterday. The file claims to be in my root Dropbox folder, but actually doesn’t seem to be there when I browse to the folder. When I try to view the video from my phone it says I don’t have permission and suggests I request access. But from my computer I can view the video (which is an ad for a NutriBullet mixer). I can see the file was created a month ago by a person not familiar to me and seemingly shared with me. I don’t recall getting a notification that something was shared with me. There are no comments on the file and I don’t know why it has shown up in my recent activity list.
I’ve gone through the security check up options in Dropbox and changed my password and enable 2FA. I didn’t notice any activity that seemed out of place regarding who or what devices had accessed my account.
Please help.
