Google Play prelaunch report - Accessibility warnings

Hello,

Since August 2018 and the changes into the Android requirements from Google, my new APKs files get some warnings when I upload them into the developper console.

I decided to upload 2 separate files for 2 arch, one for armeabi-v7 and one for x86. Some hours after the upload, Google gives me prelaunch reports with warnings only for the armv7 APK. The x86 is ok for publishing.

The error is just a warning about accessibility that says that there is no label description for the Unity Player view (it's a content labelling problem).

The english translation is: "The label of this item may not be readable by a screen reader."

As you can see, the 1st line got warnings and the second line, same APK for x86 arch is 100% clean.

I don't know what I can do to solve this problem.

Thank you in advance
