I run Zwift on my iPhone and companion on my iPad. Because the iPhone image fits better on my tv from my iPhone.
Now using companion on the ipad wastes a lot of screen space, if zwift were to enable split screen i could run discord right along side.
Is it a huge nightmare deal to make it so? I can’t believe it is if the company i eork for can do it on their apps.. i am sure zwift could make it so!
