Known Issues

If you're experiencing problems while updating your Nextcloud intance, try to disable/delete Draw.io integration app (/apps/drawio/) and then install/copy it again after the NC update is completed.
Clear PHP cache after updating the app if you have undefined method/classes errors.
Integrity check of Nextcloud core fails as we add our new MIME types and icons. This is expected and safe to ignore (issue #26).
