VoiceOver + TalkBack - issues accessing content underneath sheet, collapsing shield, interacting with content on sheet

[JuliannaR]

When the status sheet is expanded, content underneath the sheet is still available/focusable via swipe/touch navigation. Mobile screen readers announce this content as if it were a part of the visible Sheet content.

When the screen is expanded screen readers users cannot collapse the sheet.

There are some wonky behaviours where screen reader users can open the change your province nav element with an expanded shield however it happens from double tapping on any area of that sheet. Users cannot access the other elements on the sheet like information, change language etc.
