Unable to edit existing draw.io diagram

[Isabelle Poueriet]

I created a confluence page and on that page I created a new draw.io diagram.

I saved the diagram in draw.io and I published the confluence page.

I then went to edit the draw.io diagram by clicking the Edit (pencil) on the diagram.

I get the following error:

An embedded page at ac.draw.io says:

Read Error: File not found.

I can see the diagram if I try to create  a new confluence page and insert an existing diagram, however, the diagram appears greyed out and when I click on it to select it, it says I have no read access to it.

I recommend you contact draw.io directly via email if you are paying for the app.  They will get back to you faster. link: https://drawio-app.com/support/

Hello.
Maybe this will help to someone, i want to share that i had same issue.

When oppening the embedded draw.io diagram under edit confluence page, it shows the above error. 
But when i open from howering into the draw.io diagram, there is like a tab that popups on the top of the diagram, i click the first button which is edit, then saving fails, but what i did is that:
Clicked Extras, then Edit Diagram, which shows all the xml kind code of the draw.io diagram. I copy this, and create a local draw.io file with the copied code from the embedded draw.io diagram. 
Then i save that, and i reupload the file..
This is the only thing that worked for me, without contacting the support, maybe there is an easier fix to this.
