I use creative cloud on my touch screen from my Lenovo Yoga A940. Indesign and Photoshop are working fine! Only after (re)installating Illustrator I can only use my two fingers once to zoom and after that Illustrator is no longer responding on my two fingers to zoom or move. I already tried to remove my preferences. Reinstalling helps, but for some reason I can only once zoom in or out. After that no respons on the zoom again. It happens in all documents.
Apologies for the delayed response. I hope your issue is resolved by now.
If not, please make sure you have OS & Illustrator updated to the latest version. You may also try resetting the preferences of the app manually:
Close all Adobe applications.
Go to Location C:\Users\user\AppData\Roaming\Adobe
Rename Adobe Illustrator and Adobe Illustrator 24 Settings folders to Adobe Illustrator.old and Adobe Illustrator 24 Settings.old
Launch Illustrator from the Creative Cloud.
**Please note that resetting preferences will remove all the custom settings and Illustrator will launch with default settings. This way all your old settings will be saved in .old folders and Illustrator will recreate new folders with default settings.
