Hi @MAR! This is an application which uses Google Chrome inside itself. Sure, the app supports any discourse instances. You get common benefits of mobile application, such as notification alerts with a bubble, fast access to the community with a predefined login etc.
Anyway, it should be tested carefully on your environment before recommending to your customer. Thus, my proxy server blocked message and status updates, therefore our clients did not receive notifications until I found a problem on my side.
By the way, now it works.
