For Apple Store, you will need to upgrade your expo SDK to 47 (Recommended:48).
Dear Developer,
We identified one or more issues with a recent delivery for your app, “************”. Your delivery was successful, but you may wish to correct the following issues in your next delivery:
ITMS-90725: SDK Version Issue - This app was built with the iOS 15.5 SDK. Starting April 2023, all iOS apps submitted to the App Store must be built with the iOS 16.1 SDK or later, included in Xcode 14.1 or later.
After you’ve corrected the issues, you can upload a new binary to App Store Connect.
Best regards,
The App Store Team
That’s an email from Apple with the warning. expo 47 and 48 are the only built to support ios16 i believe.
For android, I don’t have an answer for what is required.
