Not compatible with Safari

[JamesNewton]

iOS 15 and higher seems to have introduced an issue with Safari where it will connect, see the page, but you can't drive the robot. Andre from Addicore was kind enough to share that they found the issue to be this bug:
https://developer.apple.com/forums/thread/685403
and the workarounds there (applied to Safari) appear to resolve the issue.

Setting safari =>Advanced=>Experimental Features=>NSURLSession WebSocket to off solves the issue

But for now, iOS users should download and use Chrome.
