Hello!
I know there have been Edge issues in the past that have been fixed, but there are a few more that I've noticed since using Windows 10 and Flarum. First one is avatar uploading, which appears to not work when browsing either my own forum or Flarum.org's forum, but works perfectly in Chrome. Second, while in the administration menu the "edit tags" button (the pencil icon next to the tag name) doesn't do anything in Edge, but it works in Chrome. The login menu also didn't work, but that has appeared to be fixed.
P.S., I believe this is the right place to post this. Let me know if it isn't and I will change the tags if possible.
