Submit button function disabled when accessing form from Adobe Acrobat DC. Form designed in Lifecycle ver 9.0.0.2

[stephank2202449]

PDF Forms I created several forms in LiveCycle Designer, which I then published for internal business use. I have found that since the upgrade of Adobe Acrobat to ver. 2018.009.20050 (DC), the submit buttons in the forms does not work any longer. When the form is opened on a previous version of Adobe Acrobat Reader, all is working fine. Do you have any idea why this is happening and is there a way to overcome the problem?
