Creating Accessible PDFs from InDesign and Reading Order

Hi

I've got an issue creating accessible pdfs from InDesign - i've read the Adobe whitepaper on this thoroughly.

No matter what I do, the order that I create frames in InDesign determines the order in the Order panel in Acrobat - even though i've rearranged tags in the Structure pane in InDesign.

Tag order is correct in Acrobat, read out loud and export to Accessible Text works great but the order panel and View > Reflow show an incorrect order based on the original order I created frames in InDesign.

I have 2 questions = is this a known issue or I am doing something wrong, and do i need to change order in Acrobat to make PDF accessible? I would guess not but i'll obviously have problems if i wanted to reflow the PDF on a different portable device (hence View > Reflow not working correctly).

The paper doesn't mention this and does mention checking all these things.

Any advice would be appreciated.
