Attachments added in Apple Mail on my Mac are not accessible when I open the same IMAP draft on my iPhone. PDFs, MP3s and MP4s do not appear, while JPEG images display normally.
A PDF sent from the iPhone arrived intact but remained invisible in iPhone Mail. It opens correctly on the Mac.
I'm using an iPhone 17 Pro with iOS 27.2, macOS 27.2 and a Posteo IMAP account.
Has anyone experienced this or found a workaround?
