canOpenURL not working, scheme now must be only lowercase?

In iOS 9 and below it's working perfectly, on iOS 10 canOpenURL return always NO...

In my plist I have this:

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>easymeetingS</string>
</array>

From what this output in console:

Jan  1 01:02:18 iPad-41-Air-v100 easymeetingOnCall S(UIKit)[374] <Notice>:
 -canOpenURL: failed for URL: "easymeetingS://"
 - error: "This app is not allowed to query for scheme easymeetings"

I can deduce that at some point they enforced lowercase on URL schemas, why? Is this bug or permanent modification? I see nowhere in documentation the enforcing of lowercase...
