Can’t change color on iPadOS 15

[mprogram 19]

You don’t seem to be able to change colors in the most recent version of iPadOS because the button is directly under the new multi screen menu feature.

Did you report it by a support ticket ?

Penultimate is not in the focus for EN - the last years it got 1 update per year, all of them plain housekeeping. The last release is one year ago - no idea if there will be an iOS15-update.

If you want to avoid being troubled by this issue for a long time, it would probably be the best to switch to another app. Personally I use GoodNotes 5 for handwriting, and there is a number of other good apps for this use case as well. Because it is about your feeling when using such an app, I would try a number of them before deciding.
