Some may say it’s not that easy for users to discover this feature.

There is a hidden site setting with a regex to control it.

You can enable it with:

```plaintext
ssh root@your.server.ip
cd /var/discourse
./launcher enter app
rails c
SiteSetting.pwa_display_browser_regex = "completelydisabled"

```
