I am been fooling around with the file attachment feature and upload action. It works really well with email attachments and uploading to Dropbox, OneDrive, etc.
However, when using the same process with Dynamics 365 it won't work when trying to attach the file to a Note record as an Attachment. This is really a necessary addition to the connector.
It looks like the "update record" when using with a note record in D365 is broken. When click on file name, it brings up file content instead... it looks like the action definition is flipped between file content and filename.
