I have a few of instances of Discourse running for different projects. They are pretty much identical, other than a couple of minor CSS differences, but are behaving differently when I try to use the “Add to homescreen” option on chrome for android. The majority work without a hitch (imitating a native app; splash screen, no URL bar, etc), however two instances seem to simply put a shortcut on the homescreen and open up in a new tab in chrome.
Are there any specific criteria that I might have neglected to set up in the two misbehaving that might be causing this? (I’ve tested it across a couple of devices, so I’m confident I’m not the only one experiencing it).

As said [here](https://meta.discourse.org/t/add-to-homescreen-banner-on-android/42973) you need https. Can you share the links?

Both are using https I believe:

Both [manifest.json](https://forum.gnosis.pm/manifest.json) is somehow broken. How they did it is beyond me.
Maybe they forgot to set a required field…

What are the required fields? And how would I go about fixing this?

My best guess is they didn’t set the `apple_touch_icon_url` SiteSetting. Try sending a PM to an admin and asking then.

I’m the admin for both.
`apple_touch_icon_url` for [https://forum.gnosis.pm](https://forum.gnosis.pm) is:
`mobile_logo_url` for [https://forum.gnosis.pm](https://forum.gnosis.pm) is:

Hahaha, you should’ve mentioned it earlier 😛.
The only SiteSettings that we use are `title` and `apple_touch_icon_url`.

Do you use any plugins? The push notifications one mess with this controller I think.

Yeah I have the push notifications plugin installed on both, I’ll try rebuilding one without and see if that fixes it.

Hoho, found it!
I think that just configuring the plugin may work. You either install and fill all the fields or uninstall.

There is a field called `gcm_sender_id` somewhere.
However, this should not happen anyway. This may fix it (still need some testing):

disabling the plugin fixed it for [https://forum.ether.camp](https://forum.ether.camp).
I’ll just disable it on both for now, and re-enable it once it’s been fixed.
Thanks heaps for the help.
