i am using the document server (docker) together with the doceditor that is similar to the PHP example provided on your website. At this time i load a document, edit it and save it back using the callback. Works fine!
But i am completely missing the option to coedit a document. If i open the document in another browser, i see the latest changes but all changes i make in this new window will be ignored.
In the editor there is no symbol/option to share a document. Also i can not find some related values in the editor configuration.
Just to be sure: coauthoring is possible with just the document server?! Or will i need to use the community server?
Thanks in advance!
