Hi there,
We apologize for the delay in response to your query. Are you still experiencing the same error or managed to find the solution?
Would you please give more information about, what happens when you use highlighter to highlight the text on Android devise? Does it freezes or not responding?
For better understanding, could you please share the screenshot of the same? For detailed steps how annotations work on Android, you may please refer to this link: Acrobat Reader Help for Android: Help Home
Thanks,
Akanchha
