Microsoft released Microsoft Edge 91 yesterday, and users have been reporting constant nag screens, bugs, and problems using the new version of the web browser. The most annoying issue is a new Microsoft Edge nag screen continuously shown on startup asking users if they want to ‘Use recommended browser settings’ Users have also reported that the browser Edge is no longer honoring their configured startup page and is opening the New Tab page instead. BleepingComputer was able to reproduce this bug after we changed the startup page to Bleeping.com.
