There seems to be a lot of source on this issue. At first my EmailComposer cordova plugin would not launch either but according to the sources I found… a simple add the config.xml of this line helped!
<access origin="mailto:*" launch-external="yes"/>
Same issue was fixed! href-tel would not launch the telephone but adding
<allow-intent href="tel:*" /> fixed that!
What I found was that adding…
<access origin="sms:*" launch-external="yes"/> would fix the sms issues but it does not… Does anyone have a fix for the cordova sms plugin to launch in iOs?
Android works fine…
