Dear Google. If I promise to set Gmail as my default email client on iOS, will you then let me keep Safari as my default browser when clicking a link in that app?
It just tends to regularly forget that I told it to save my choice of Safari.
iOS GMail App > Settings > Default Apps
You cannot choose Firefox or Brave but you certainly can choose Safari.
This shady behavior (calling a web view "Safari") is one of the reasons I gave up on Gmail.
