Accessibility issues have been identified with the latest releases of TeamViewer (version 15.33.7) which affect its support for screen readers including SuperNova and Dolphin ScreenReader.
The accessibility issues are with the main Teamviewer application not the Quick Support module that we supply with the products, so this is an issue for anyone using a Screen Reader and supporting their end users.
When you use the arrow keys or the tab key to navigate the screen with a screen reader, the speech will not announce the focus information, it will only echo key presses.
We have been in touch with TeamViewer directly and they have replicated the issue, the issue has been escalated internally, and they are committed to working on a solution.
TeamViewer are yet to provide us with details on when a fix will be available. The suggested workaround is to roll back to an older version of TeamViewer until the issue is resolved.
