Adding Brave as a default web browser option for Newton Mail IOS is a no-brainer. This browser is becoming more popular and said end-users need to be able to redirect email links to open in this browser preferably.
I feel Newton doesn’t need to even bother about what the system’s default browser is, especially it’s now possible to configure that default on iOS. Newton should just open links on whatever browser has been set as default on the operating system level.
