No Send button when Send file by email

[HarborSkip]

I feel very dopey asking this, but here goes...

I'm using the latest version of Adobe Acrobat Pro DC on the latest Windows 10 and specify gmail to send emails.
I Edit a PDF.  While viewing it, I click the Send a file by email button.  I enter an address to send it to.

At this point the online user documentation leads me to believe I should see a Send button at the bottom, but I don't.  See the attached screenshot.
What am I doing wrong here?

Hi there

Hope you are doing well and sorry for the trouble. As described, you see no send button when send file by email.

I tried to reproduce the issue on my end and getting the option 'Continue'

Please try to repair the installation from the help menu (Win Only) and see reboot the computer

Also try to reset the Acrobat preferences as described here https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-defau...

You may also try to create a new test user profile with full admin rights in Windows and try using the application there and check.

Regards
