We're receiving an error when we try to open a document from a SPO library which contains a signature line object it the document. The message is "Sorry. Word ran into a problem while opening this document in a browser. To view this document, please open it in the desktop version of Microsoft Word."
I accept that Word for the web contains basic editing and formatting capabilities, and that for more advanced features you would need to Open in the Word Desktop App. Looking for official MS documentation that speaks to this. Thanks.
