“Resume watching “ on a movie I’ve never watched or heard of.

I have the Roku fire stick on my tv and I have the app. on my phone . I’ve never watched anything on the app, just the fire stick.

I just opened the app today to see if there was a “tv guide” feature and noticed a “resume watching “ on a movie I’ve never watched.

I don’t share this account with anyone and no one should have my password . Should I be concerned?
