Hello @Cavediver
Thanks for reaching out. This sounds like it could be related to how the form is being saved and returned to you, so let's dig into a few details.
Could you confirm the following?
Which application did your client use to fill out and save the form (Adobe Reader, Adobe Acrobat, or a browser)?
When you open the returned form, do the fields still appear as fillable form fields (with the usual blue/gray highlight), or does the form look flattened, like plain text with no field borders?
Did you originally create this form in Acrobat, and did you enable "Extend Forms" / Reader extended features so clients filling it in Adobe Reader could save their data back into an editable form?
Do you see any specific error message when trying to add or change data, or do the fields simply not respond to clicks?
If the fields have become flattened (no longer editable, just static text/images), that usually happens when the form is saved as a flattened copy rather than preserving live form fields, which could point to how it was saved on your client's end, or whether "Extend Forms" was enabled when you first created it.
Let us know how it goes.
Regards,
Amal
