I created an interactive pdf in Indesign, exported it, and opened it in Acrobat DC (both are the most recent version as of April 3rd, 2021). The Text in the interactive text boxes in Indesign are flush to the top left of the box. However, in Acrobat, they have a slight indentation from the left and an enormous gap - nearly an entire line of text high - at the top. I have them formated to multi-line and turned rich text on, (which improved a leading issue), but I haven't been able to solve this.
