Hi @malakmoaty
Try the following
1. Delete the Timeline component and publish it. Sync and preview the site. Make sure the timeline component is not appearing.
2. Add it again and publish.
3. For Annotations (Notes) table > add the appropriate web roles. For ex: In the Administrator web roles add your contact and sync it.
Press ctrl + F5 - hard refresh and preview the site
Good luck
Hope it helps.
