Multiline feature in Adobesign webforms freaks out occasionally - why?

Hello Adobe Community,

I have several Adobesign webforms originally created in 2023 and 2024 that contain larger text boxes (for research descriptions) using the Multiline feature, with the font set to Auto. I have made small updates to the forms over time, like tweaking drop-downs and adding color to text, etc. Overall, the forms have been working perfectly. However, today and one other time earlier this year, it seems those large text boxes stop working. Today's issue was the text not showing up once the form was sent to the next signer. Earlier it was the font size stuck on 400 pt and not minimizing. In both cases, I went in and changed from auto font to either 10 or 12 pt, but why would I have to do this? What causes this? Updates?

Thanks in advance for any help or tips!
