Sending Email iOS13 Issue
When iOS13 operating system was released from Apple, it breaks features in older apps made for iOS12 and earlier. The issue is that it seems that there is no “Send” arrow or button to complete sending your email. There is, it is just the same color as the background. You just need to keep clicking the top right of that window as shown in these video tutorials below.
We are currently addressing these issues and will have an update ready soon once it is vetted and approved by Apple. Targeted release is in October 2019.
