Note: a part 2 of this announcement will be sent soon.
Within the next few hours, you’ll get a notification (hopefully via Add-on Updater) that a new update is available for Windows 10 App Essentials. Version 19.11.1 of this add-on includes a hotfix to allow continued operation of the add-on in latest NVDA 2019.3 alpha snapshots, specifically in regards to braille support in emoji panel and other Windows 10 areas. This came as a result of backwards incompatible change made to NVDA’s source code, which is affecting certain add-ons (a notice was sent to add-on authors a few hours ago).
Note: please do update to 19.11.1, especially if you are using NVDA 2019.3 alpha snapshots.
