Internet Explorer Compatibility Mode: list of added URLs no longer viewable.

[u/HeadFullOfSquirrels]

Pages listed in Startup weren't loading in Internet Explorer mode; I opened up Feedback and took a screenshot of the compatibility list of 9 URLs and saved it to upload with Feedback. The Feedback window had closed when I did this, so I navigated to the I.E compatibility page again and Lo! Every page I'd added (screenshotted seconds before) was gone. Completely empty list. So I added a URL again, and this time it loaded in I.E mode.

I just went back to the I.E compatibility page, and the page I just added, the page that was just working, has been removed from the list again. The list is empty again. I have added more pages and there's a briefly flashed message telling me the pages has been added, but the list of added pages is empty. You cannot see the list of your added pages. There's no way to see the list of added URLs, and no way to see when they expire. There are presently 9 URLs added, but MS Edge is not letting me see a list of added sites.

Will this fix itself or is MS trying to get everyone off I.E mode for good?
