I am a long time adobe user. What I've noticed over the last few years is that whenever I edit and format fillable Adobe Acrobat PDF forms (such as date fields, set up tab settings, so the user can tab over to the next field, add customized field auto- calculation settings, etc.), then email it to someone, that end user always complains that some of the fields are not auto-calculating correctly, or some of the tabs orders I've created are not tabbing over correctly. Now I know I format it correctly. I save the file and test it 3 - 4 times before sending it over to make sure every function, every field is working properly. However, still, every single time, there are at least 5 out of 20 forms that have this issue - and it's always random. When I test and download the email to see if it is working, sometimes I get the same issue (even though I check settings and none of the settings have changed) and other times, I can't recreate that issue. Is anyone else having this random issue? I've updated my computer, restarted it, tried on both mac and windows, double checked the end users adobe acrobat software and version to make sure both were the same - I've literally done everything I could possibly think of, but this issue keeps happening randomly and I am so tired of it!
