Scanning TV Shows

How do I stop Plex scanning content during the day, I have it set to scan after 1am

Disable automatic and periodic library scans.

Instead, enable library scans as part of the scheduled tasks. Set their time window as you see fit – but it should be when your server is typically not busy with playback.

Thanks, I’ll check it out

Do you mean disable “Refresh library metadata periodically”

Yes, both automatically and periodically.

Thanks
