I am about to migrate our current project from Ionic 3 to Ionic 4 (with Ionic cli 5 and Ionic UI library V4). However, our current Ionic project supports IOS 9 and Android 5.
I have a feeling that once the project has been upgraded, both IOS and Android users will have problem. So can anyone please let me know what are the minimum versions of IOS and Android that Ionic 4 supports?
Thanks very much in advance.
