Hello,
I actually found and edited the text I need to change in the Hubspot form, but I cannot find it now to change it again. I can find it in View but not in the Editor (see image).
It's the text right before you upload a file ("the letter"):
In the form editor, I look at the first question, and I go to the BASIC and LOGIC tabs, and click on the 2 CONDITIONAL FIELDS thinking the text about the upload will show up, but I can't find it.
Hope this explains it. Thanks.
