Target minimum iOS version not working after set to 9.0 (iOS 9.3.5)

Hi,

I am building my app without any errors, I have built both development and App Store versions. I have set the target minimum iOS version to 9.0 in the player settings.

I have tested on new iOS device, iPad and iPhone, they work without any issues. I have tested on older iPad and iPhone and am getting a blank screen after the game launches. This is only with the development version that is installed via cloud build install feature. The iso Store version that I am testing via TestFlight, tells me that the app doesn't meet the minimum requirements, when I attempt to install via TestFlight.

Does Api Compatibility Level have anything to do with this? Currently set to .Net Standard 2.0.

Can anyone help me with this?

 

Changing Api Compatibility Level did not help, I am still stuck.

 

I think its something to do with Xcode, trying a different version now.

 

I am still working on this. I am very confident that it has to do with using "metal" as a Graphics API (as per https://developer.apple.com/library...tibilityMatrix/DeviceCompatibilityMatrix.html)

I am removing metal and adding OpenGLES3 and OpenGLES2.

At the end of the day I am not sure if removing metal and adding the other two is a good thing. I would appreciate any feedback on this.

 

This was 100% the issue. Now fixed and running on older iOS devices, however ....

It was really a waste of time, my old iPhone 5 or 5c (iOs 10.3.3), was really slow and will definitely lead to bad reviews on performance alone. The same can be said of my old ipad 2 (9.3.5).

In conclusion I am adding metal back and am upping my minimum version of ios to 12.

I hope my frustration helps someone.
