I made the change and think it's great.
The Miaomiao is no longer required and the readings seem to be more accurate.
I assume if you are a Miaomiao user, you are using a third party app.
If all you need is the alerts when your levels get too high or too low, you can get these with the official app with official support and no need to deal with enthusiastic geeks who only speak tech-talk".
The LibreLink phone app is all that is needed. You can review the historic data via LibreView ... as can your diabetes team if they are interested.
If that is not good enough motivation, I expect Libre 1 to be desupported in the future so you are likely to reach a point when you have no choice.
