I stumbled across a Wyze Support article about Brave browser, which said this:
look for a setting named Allow app links to open in apps outside of Brave or similar, then turn on this setting
That seems a lot like what @williams1 did with Edge.
Then I found a topic on a Samsung community site that suggests the following (in the video embedded in that post):
- Open Samsung Internet Browser
Settings.
- Tap Useful features.
- Tap to enable Open links in other apps.
I don’t know if that’s actually the solution for any of you Galaxy users, but I hope someone will try it out and report back for the benefit of others!
