Another minor: concerns ios11, Readdle documents and Safari. If I use Create PDF, on Safari, and export to Readdle Documents, I am unable to transfer the PDF onto either a Windows shared drive or on my router shared drive. I can transfer other PDFs, e.g books, etc., from Documents with no problem and if I export the pdf from Safari to File Browser, I am able to transfer on successfully. Readdle Documents has several tries to transfer but fails in the final <1%.
Not sure which is to blame, but could be something to do with ios11/Safari pdf formal. No doubt it will be fixed in due time.
(Also, if anyone is using it, To PDF, by dar-soft no longer seems to produce PDFs with ios11 and dar- soft had said tha they would cease supporting ios a while back.j
