Hi Matt, thanks for your reply and instructions, it worked but not very intuitive, i’m having some difficulties, and i have serached that topic in the community without luck

the other issue now is that after button1 is pressed “so is active after text input” i need the button1 to send a what’sapp ot sms to a number, but only lauches the sms apps without sending it i the background (i entered the phone number to sms to) i will also need at the end of next screens to have a “submit” button that will email the information entered in the app previously, i have tried the “email to” block but again it only lauches the email app not sending the email automatically in the background, is there any fix on this? otherwise the app is not going to be userful, thanks for your help

To just send the email or message in the background would likely be much more advanced. Depending on the service, you may be able to use their API to send a message. We have not tested this so it would require some experimentation. Our share blocks can only open the default email or messaging app and send the message that way.
