Why i cant send estimates to my customers from my phone app? Just lets me to save it ... wich is not helpful... on computer works fine but its not good enough for me

Hello and welcome to the Community, em-mineikis-gmai

After tapping save on the estimate in the app, the following screen will show an overview with a blue banner 'send estimate'. From here, you can edit the subject line and body of the email, as well as add or edit the recipients address.
