TeachingTip customization des not work

Good morning,

I read the discussion [https://github.com/microsoft/microsoft-ui-xaml/discussions/7811]
I am having the same issue and the suggested solution by @marcelwgn is not enough for me.

I need to customize the behavior of my TeachingTip giving it a different with in different sections.

I tried by setting the following in different pages but it did not work.
900

The only place where this setting is applied is when I put it in the App.xaml, but this does not allow me to fulfil my needs.
This seems a bug.

Can any of you advice me on how to proceed? Do you have any workaround for this?
Thank you. Best regards,

Start with the TeachingTipMaxWidth resource shown in the issue and compare how it behaves in page resources versus App.xaml. Review the linked discussion for the suggested solution, then reproduce the page-specific width behavior and document or verify a fix when different sections can use different widths.
