I tried Mathematica in the Wolfram Cloud when it first came out. I found it riddled with glitches. I'm attempting to give a second shot now. I tried plotting the following code:
It returns a pink cell where if I hover over it says "Type Error: Null is not an object..." Do you get the same error? I've tried two different browsers with the same result.
So far I'm not too happy with Mathematica in the cloud. I'm looking for a solution present my mathematica files in the classroom with an iPad. I really wish Wolfram would make a native CDF player for the iPad. They had a working version in 2012. But I was told a few years ago that they put it on hold to work on the cloud. Bummed about this as you can do a lot more with a native player. Does anyone know if Wolfram is planning to make a native player in the near future?
I have an iPad pro with plenty of processing power. I hope they will move in this direction soon.
