Connecting to classroom via ipad launchpad

I am looking for the best way to have students use Tynker on their ipads.
When they log in with their Google accounts and go through the Google Classroom app they see their assignments. But, when we use Safari on the ipad we get an error. “Your browser may not be compatible with Tynker” https://goo.gl/photos/J8FS4TVuEzDQsgmN7
When we log in with their student account directly on the Tynker app, we don’t see their classroom assignments.
Any help appreciated.

The Tynker curriculum is not available on the iPad. The projects in the iPad sync to the web, so there is sync there, but the coursework is only available on a browser using a laptop or PC.
