Our team is rather new to SharePoint. We are using Office 365 SharePoint Online. I am not sharepoint administrator and cannot use powershell or any alike app. I need help as I am a user with "Full Control" site permission. I built a list for sales and after the team started work and all of a sudden 2 weeks ago the list does not accept any add or update to items. The delete List option also disappeared. I tried all available solutions in forums but no way. Any help?
Kindly Help if you can.
