showToast - usefulness?

I'm considering using WatchUI.showToast to indicate when a certain user setting was changed by the watch face because it's incompatible with another setting they chose.  For example, when a user selects option A, I need to turn off option B.  I want to avoid any confusion / bug reports when this happens.

But in my device testing (Epix 2 Pro 51),showToast can only display about 19 characters on one line. I would have expected text wrapping onto 2 lines (like I see in the simulator) or a way for the user to tap/click to see the rest of the message (like when other notifications arrive). 

It doesn't wrap the text or provide any way to see a message longer than 19 chars. 

  • Is that correct/usual? 
  • What have other dev's experiences been using WatchUI.showToast?
  • The other issue for me (as a user) is that it disappears after a few seconds. So either I can completely miss it (though in your case that's probably less of an issue, as they'll see it immediately after they click a button) or not have enough time to read it (especially if you would be able to display longer text - that might be displayed with even smaller font)
