Hi Migueld,
With the new update, we have changed the gesture for highlighting text from drag to long press-and-drag.
This is an as designed behavior.
Here are the steps to highlight a text:
- Tap on the commenting tools button to get to the commenting mode.
- Tap on the highlight button.
- Long press on the beginning of the text you want to highlight until a magnifying glass appears
- Drag the sentence to highlight the rest of your text.
Alternatively, if you do not have the commenting mode active, you can also long press on a word, and commenting options will appear for you, including highlight.
We appreciate your feedback on this.
You may share your feedback on this with the team over here Adobe Acrobat for iPhone and iPad - Feature Request/Bug Report Form
Let us know if you have any questions.
Regards,
Meenakshi
