In service portal, there are many date/time fields displaying in terms of how long ago events occurred (minutes / hours / days / months / years ago), however screen readers fail to read abbreviations correctly causing confusion to users.
1. Start VO and use Safari.
2. Navigate to /sp.
3. Open any form (e.g. anything under 'my open incidents').
4. Move through the page using the right arrow (forward) and left arrow (backward) until you reach the contents of the activity stream. Note that the times ago are read exactly as displayed without the meaning of the "m", "h", "d" abbreviations.
This problem is under review and targeted to be fixed in a future release. To receive notifications when more information becomes available, subscribe to this Known Error article by clicking the Subscribe button at the top right of this form.
