Hi, this issue should now be fixed in the latest UI update (version 1.0.860).
The update should apply automatically, but if you don’t see it yet, go to Settings → Update and click the second “Check for updates” button. Then close and reopen the app.
Once the new UI is applied, you should see Pop-up notifications treatment again in Notifications settings.
We apologize for any inconvenience this may have caused.
