Apple store rejection:latest iPad mini display (sigh)

[trevix]

Today I was going to update my mobile app on the Apple store and Transporter reported the following warning:

WARNING ITMS-90901: "Missing full-screen support for the latest iPad mini display. The “SegnaPunto.app” bundle includes UIRequiresFullScreen=YES in the Info.plist or supports only a subset of UISupportedInterfaceOrientations, and is built with the 14.4 SDK. To take advantage of the full screen size, recompile with Xcode 13 and the SDK for iPadOS 15 or later."

Since I am on a Mac (Catalina) wich cannot install MacOS 11, for now, since I will have to shell thousands for a new Mac, can I publish the app anyway?
Or, after having done all the tasks, Apple will forbid it because it doesn't support the "new iPad mini" or I will have other kind of problems?

Thanks

@trevix: That looks like just a warning - so shouldn't stop it being reviewed / accepted I don't think.
