I have a power app with an edit form connected to a Sharepoint list. I include the attachment field on the form but when users attach documents, it does not hit the sharepoint list. Is there some things I should be checking? I can provide more information but I am new to PowerApps and I do not really know where to start.
Check the Update property of attachment data card. See if the formula is "AttachmentControlName.Attachments".
Did you add the attachment data card from the "Edit fields" link of the Edit Form control on the right side of the app here?
You could try to delete the attachment data card, and then readd it by checking the Attachments checkbox in above screenshot to have a test.
