I got 2 Tapo T110 door sensors, got them set up easily, and shared them with my wife so she can also see the event log on her phone. Great!

They worked so well that we bought another T110 door sensor. Set up with ease again, but this time I'm unable to share it! I hit share as before, and my wife gets an invitation via phone notification - but when she taps it, it opens the Tapo app, but nothing happens; the device is not added.

There's no error message or anything like that, and we've tried the same process several times, have rebooted the Tapo hub, updated our Tapo mobile apps to the latest version, but still the same result.

Any ideas? 🙏
