Important note about accessibility

[ADDED 1/15/2020] We are aware Narrator and NVDA users that seek the latest release of Microsoft Edge based on Chromium may experience some difficulty when navigating and reading certain web content. Narrator, NVDA and the Edge teams are aware of these issues. Users of legacy Microsoft Edge will not be affected. NVAccess has released a beta of NVDA that resolves the known issue with Edge. Further information can also be found in the In Process blog post that goes into more detail about the beta.

For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.

Thanks,
BLB
