Quote:It is a new week, which means it is time for a new Edge Dev build. This week, Microsoft is releasing build 85.0.552.1 to the Dev channel with a few new features and a bunch of fixes and known issues. The new features are mainly geared towards adding support for a few new management policies, such as for the new tab page’s search box.
 
As for known issues, the company today posted a blog acknowledging the issue with AdBlock and AdBlock Plus extensions causing issues with playing YouTube videos. The company is looking for more feedback while it works on a fix for the issue.
 
Here is the list of the known issues:
