It works after having upgraded to Android 15 (LineageOS 22.1).

Same problem on a galaxy tab S4, and cannot update it above Android 10 so I'm stuck with being unable to use the stylus button...

This actually works partially in version 0.25.1, but was broken in 0.25.2. In 0.25.1 you have to press the button after putting the pen on the screen to start erasing.

However, starting with 0.25.2 eraser does not work at all.

Same issue at v0.25.2 (F-Droid) on Samsung Tab S6 Lite.

• If the stylus button is pressed before the stylus touches the screen: toolbar shows that the eraser is enabled, but touching the screen with the stylus has no effect.
• If the stylus button is pressed after the stylus touches the screen: toolbar shows that the eraser is enabled, and touching the screen with the stylus erases objects.

After upgrading to v0.26.2, the eraser has no effect no matter whether the button is pressed before or after touching the screen.
