  • Hello,

    Thank you for providing this information about the issue. After thorough testing, we are unable to reproduce this problem in Edge with the information at hand. Please update this case when you can provide more details, such as if you need to be logged in to lastpass to repro and a screenshot of where you went to install the app, for clues what we are doing differently.

    Best Wishes,
