Hi,
I'm sad to hear you're experiencing changes in the context menu within SharePoint Online, particularly the absence of important functions like "Request Signature." This issue has been observed by other users as well, and several factors might contribute to such changes. Here are some steps and considerations to help restore the previous functionality:
- Switch to Modern Experience
- Modify the Document Library View
- Check Permissions and Licensing
- Review Site Collection Features:Ensure that all necessary features, especially those related to document management and signatures, are activated.
- Clear Browser Cache and Cookies
