MM Shows a plain Black Screen on iOS 9.3.5 device

@shiroe Mobile Safari on iOS 9.3 is obviously missing some features. If a module is using a function not supported by this version of Mobile Safari a black screen might happen.

You only can debug this using Mac.

@idoodler FYI default modules only it still shows the same, I have a bit more time tomorrow so I’ll try reducing one by one to see if i can find exactly which doesn’t work - though I feel it’s likely going to be all of them

Same problem here… iPad 2 with iOS 9.3.5 and I’m getting a black screen… I tried with Google Chrome, Dolphin Browser but no good luck.
A work around: Install VNC Server on RPi, and a client on the iPad. Go to fullscreen mode, and voila!

@pipe-line I think we have an iOs 9 device at work. I will debug it tomorrow night. What modules do you have installed?

@idoodler I started with Current Weather and Weather Forecast and then only with Current Weather, but no lucky.
Thanks!

@pipe-line ok. I just gathered the iPad. Its an iPad mini running iOS 9.3.3. I hope I won’t forget it until I get home:)

Issue has been identified. I am just preparing a pull request. Hold on tight!

Lol. This issue has already been fixed on the 8th of April 2018 by Chris Pickett. It is available on the develop branch. It eventually will be merged with the masterbranch.

@idoodler thanks! I will try develop branch this night :)

I also identified the issue. It is related to the use of Promises, a feature of ECMAScript 6, which is not supported by iOS 9.3.5. The feature is used in multiple javascript files that are built into the core of MagicMirror2. I believe it can be fixed with a polyfill.
