MM Shows a plain Black Screen on iOS 9.3.5 device

 Force close the app. Then upgrade your app may solve iPad screen black problem.

 This is still an issue. I have MM 2.12.0 and an iPad2 running 9.3.6 (the highest it will update to). The iPad2 gets the black screen when I go to MM http://ip-address:8080. My iphone 7 renders the page perfectly as do all of my Mac and PC laptops. I had an issue on an older laptop but updated the browser and that fixed it. I can’t update the browser on the iPad as the newer versions need iOS 10+. Any suggestions? Thanks!!

 @spoonek did u try chrome browser on the iPad? 
- 
 @sdetweil Yes, that is my default browser. I tried Safari as well, no luck. I then tried to install Firefox and got the same issue, needs version 10+. Thanks!! :clinking_beer_mugs:

 @spoonek if u have the black screen using chrome, open the dev window (see the menu) and select the console tab and scroll up to see any errors

 I guess this is the problem of iOS. 
 Have you tried to update the iOS and the app? May be these will help:
 1.Update the iOS and the app to the latest version
 2. Force Restart iPhone to Fix iPhone
 3. Use iOS System Recovery to [fix iOS system free for mac](link url=“https://www.tuneskit.com/ios-system-recovery-for-mac.html”)
 4. Using iTunes to Fix

 Any news here for a workaround? Tried it with my iPad 2 (9.3.6) and different browsers… also installed the developer branch on my server.

 @magicx no, and it will be harder in 2.15, as more code has been converted to es6 notation which the early ios browsers don’t support
