If you install MaintenanceMode.Site on Umbraco 10 and enable a content freeze you get an API Error when attempting to save content.
in backofficeUserAccessor.BackofficeUser.GetId()
I don't think the API has changed, but there might be a binary compatibility issue with it.
Upgrading the package project to Umbraco 10 seems to resolve this.
