I teach Sunday School and have a group of 58 members to whom I send group emails with attached lesson plans. I was having a problem with having an attachment being attached to an email following the latest update to iOS 13. I wrote an email very early Sunday Morning, before 5:00 am. Peter, the app developer, must have been up praying I assume!, got my inquiry and responded with the solution in a matter of minutes! I was really impressed with the rapid and helpful response and love the app. You won’t go wrong using this one in either the free or the upgraded version which is very reasonably priced at $3.99.
