I'm trying to collect what are the minimum supported versions of desktop and mobile browsers and OS versions for the Communication Services and the Sharing Services packages. On their respective pages, I see mentions like Chrome 58+ and Firefox 52+, Android 4.4+, etc. These are very old versions. Also IE 10 and 11? Is that correct? I'm wondering if this is still the minimum supported, or just the page was not updated.
Same for Android, version 6 is mentioned for the Sharing Services, and version 11 is the latest.
