On Mac OSX High Sierra, 10.13.3 (17D47), Default browser set to Chrome
Just installed fresh Sidekick (Version: 1.5.1-v.2018.2.26.1) and a fresh Nativescript (3.4.3).
When starting Sidekick starts, I am prompted to login or “connect with” various services.
Every link I click on this modal dialog, opens the chrome browser in the background, with an empty tab. I cannot connect using my GitHub account (which I prefer to do), and if I try to register for a Telerik Account, I still get the empty browser page.
