Animate - pressure sensitivity button missing

Hello, 

I saw so many posts with the same subject but yet didn't get any answer from it.

I have an xp-pen tablet and I used Animate all year with but since a few weeks and with the latest update, the pressure sensitity button is missing in the toolbar (at the bottom). I contacted someone from Adobe over the phone that couldn't give me an answer yet and works on it. I have the latest version of this software, my drivers are updated and working, and of course I already drew a lot with this option missing still. Where the issue is coming from ?

Thank you very much in advance for your answer.

Best regards,
