I have just started using O365 Flows and am very excited to use it.
But during implementation of OOB Flows Template "Save my email attachments to a SharePoint document library" found few issues as mentioned below:
1. Create File Flow: When tried using the combination of "Sender - Subject - Name", the flows failed, because of some special character ":" in a subject line. My concern is, if the option is there then these special character issue should be handled.
2. Attachments : Strangely I would be getting almost every attachments including images used in Signature etc,, which is something making clutter the SP Library with non-required attachments.
