Installed "Send To Kindle" on Firefox 105.0.1 (64-bit). Added my kindle to "Send to Address" and selected "@free.kindle.com." Copied and pasted (Ctrl-C, Ctrl-V) a 320-page .pdf to "Paste content here" and selected "Send." Got "Please match the requested format." Tried again with same document, but from .docx source with same result. What does "Please match the requested format" mean? How do I fix this?
