Hello,
I was looking through notifications and then the drop-down menu appears. However, it does not change with what you press and / freezes on an option.
Here is a screenshot, I cannot currently record screen. (This only happens on mobile version 2.4.0 beta9)
I can reproduce a similar problem when in Notifications. I select Responses or Likes or Mentions or Edits and the correct list appears but the dropdown always shows All.
Android 9 and iOS
Using both Chrome and Discourse app
