I Face Severe Lag Using Goodnotes on Samsung Tab S9 FE

I'm using a Samsung Galaxy Tab S9 FE, and the main issue I’m facing is with the Goodnotes app constantly lagging and freezing while I write. It becomes extremely difficult to take notes or study efficiently. At first, I thought the issue might be with the tablet itself, so I had it checked. However, everything on the hardware side came back perfectly fine. The lag only happens within the Goodnotes app—as soon as I switch to another app, the pen writes smoothly and everything works just fine.

This clearly points to a problem between Goodnotes and Samsung Tab S9 FE compatibility, which is frustrating because both are premium tools meant for productivity. I bought this setup specifically for digital note-taking and expected much better performance.

This needs to be fixed immediately. I’m calling on Samsung and Goodnotes to resolve this issue with an urgent update or workaround. Don’t let customers regret choosing your products for serious academic or professional use.
