Illustrator window disappears on iPad when disabling Touch Bar in sidecar

Question

I am using MacBook Pro 2024 macOS Sequoia 15.5 and iPad Pro (2019) iPadOS 18.5 and Adobe Illustrator 2025. Everything is currently up to date.

When I connect my iPad to my MacBook via sidecar, everything works with Touch Bar showing, except the Apple Pencil tracks 1cm or so below where I place the tip of the pencil. When I disable Touch Bar, the pencil issue is resolved but then Illustrator disappears from my iPad screen. All I can see is the MacBook desktop and Finder/File/Edit/View etc bar along the top and the side bar on the side. When I click "show Touch Bar" the illustrator window appears again on my iPad screen.

Has anyone had this issue and what is the solution? I'm thinking it may be a Mac issue and not Adobe since other app windows also disappear but figured I'd start here. I'm posting a little video where you can see how the iPad screen blanks out to the MacBook desktop when I select hide Touch Bar, and it reappears when I select show Touch Bar.

@loo_7180 supposedly this is a known issue. But, this is indeed more of a macOS/Sidecar issue than an Adobe Illustrator! A common workaround involve disabling the 'Touch Bar' or if you're using Sidecar wirelessly, try connecting your iPad to your MacBook Pro directly with a USB-C cable. This can sometimes provide a more stable connection and resolve display-related anomalies
