I have built my react native to work for iPhone6. That is, the 'flex' values are geared for this phone. I want to upload this app to the app market, but there are so many different phones (iPhoneX, iPhone8 etc...). How do i release this app to the app market and cater for all these different screen sizes?
I know the different 'flex' values i need for each of the other phones, but how does the app market know which version with the right 'flex' is needed? I can't upload multiple versions of the app with different 'flex' values.
