Pause/Resume Timeline triggers cause Screen Reader to start over at the beginning of the slide focus order

Hello again - 

Sadly my attempted solution did not solve the problem.  I have opened a support case, however I am also hoping that someone on the forum might have an approach that could address the problem while the support team looks into it.

I have uploaded a generic sample file that illustrates the way my interaction is set up.

The desired screen reader behavior is:

1) Display/Read slide title and first text box.
2) User selects Next when button enabled - then display/read content of layer (currently it is NOT reading the text box, only the close button)
3) Select Close button - close layer and resume base layer timeline and read next text box from where it paused when the layer was opened

Testing with NVDA - the read order does not seem to follow the focus order well at all, but particularly from the point that the layer is displayed on.

Thanks for any insight on a better approach.
