Limit to number of movies playback progress

[Andromeda1 2]

Not finding this on search but is there a limit to the number of movies which Emby server can keep tabs on the playback progress of? I mean the green progress bar that shows how much of the movie you've watched. I've got a feeling it's forgotten some of mine. More recent ones are fine.

Hi, no, there is no limit to this.

Thanks for the info. I must be mistaken.

Why do you think some have been forgotten?

I found out I had accidentally clicked the Mark as played checkmark on a parent folder when in the web client. User error. Thanks
