I have synced my laptop browser with my phone browser, but clicking phone nubmers on a web page does not send it to my phone. It pop up a dialog box that wants me to choose an app to handle the number. How can I fix this so it sends the number to my phone
That is not something that the browser/Sync can do. You can see the list of Syncable data types in brave://settings/braveSync/setup.
To perform the action you’re asking, you’d need to link your system (not just the browser) to your phone via some means.
I used this very often in Chrome, will it ever be added to brave?
