Hello Jeremy,
You told us that Papers has switched from an opt-in infobar to a toast, a visual message (that is read out by Orca), somewhat similar to how web browsers enable caret navigation.
Do I understand this correctly, there is no menu in "Papers", you no longer have an infobar which wasn't default but required an opt-in selection but "Papers" features something called a "toast" which is a visual message that is read out by Orca.
Does this "toast" feature need to be turned on?
Best wishes,
David Ring
