I'm guessing that there's a lack of answers because this is hard. Libre can only send automatic readings to one device, and that will be the omnipod. And Omnipod won't talk to anything.
Yes, this isn't great. And the makers of Omnipod seem to have no interest in improving their software to make things like this possible, or indeed listening to their end users at all. No smart watch support isn't top of my list, but it's quite high.
Gripe 2 : Why can't we have the current reading available on the lock screen of the device without needing a PIN? (means you need to take gloves off to see, and is hard in wet conditions).
Gripe 3 : Why isn't the device backed up? If you lose it or it dies, you need to start from scratch with a new one, and all the learning it's done over the past months is gone.
Gripe 4 : Activity mode is useless. Can we have pause support in auto mode to save about a million button presses?
Gripe 4a : Can we turn automatic mode back on from pause in one go, rather than having to unpause then switch?
Gripe 5 : Can we have a smaller device? (which is of course related to the starting point of this conversation)
Any others?
