Unable to submit Editable PDF form to web-service on mobile devices

Ok , are you saying that when you click on the submit button using Acrobat on a desktop computer, it will automatically open the URL in the default browser specified in Adobe Acrobat or defaulted by the operating system?

I used that old link for a solution that worked for me and the explanation is still valid when it comes to trying to open an URL embedded in a PDF form using Adobe Acrobat mobile.

What is strange in your case, is that with the use of the button and javascript it should've work.

If you are subscribed to Adobe Acrobat Pro you should also be able to unlock some premium editing features in the acrobat mobile app. You have to log in to with your user  account using your mobile app.

So what I'm thinking is, if it would make a difference if you try to use the submit button again but while you are logged in to your account.

I know this does not make any sense , but is just trial and error.

The other thing I can think of is if you can share the code that was used for the submit button and briefly describe the steps that were followed when the URL was incorporated in the script.

Hopefully soomeone can try and reproduce the issue and help here with a better answer.
