Office Online Server with OneNote

I’ve been using NextCloud with OOS for years now and it’s great. It works perfectly with Word, Excel and PowerPoint. But when anyone tries to open a OneNote document, the error “Something went wrong and we couldn’t load this content.”

This occurs for all users, and any OneNote file. Even a brand new empty OneNote document.

Office Online Integration is 2.0.0.
NextCloud is 25.0.5.
OOS is up to date.

I did check the https://office/hosting/discovery, and all of the OneNote stanzas are present.

Has anyone had success using OneNote? Is there anything special I need to do?
