Cannot fill in fillable form
I've seen this question posted before, but their solution didn't seem to help.
I got a .pdf as an e-mail attachment. I'm using Acrobat Pro DC 2020.012.20048. The document has fillable fields.
When I go to Fill & Sign, I can click on one of the fields. I see a flashing vertical line. But, when I start to type, nothing happens.
I've looked at security and other obvious "maybe it's this" places, but nothing comes up.
I assume I'm missing something simple.
What should I check?
Thanks in advance.
