Just reporting that workaround found in topic about Google pixel and Suunto 9 Peak Pro watch worked also on my Xiaomi 11T Android. Suunto 9 Peak Pro: problem connecting to Phone Google Pixel 6

@p3079 when you reset you do not lose the updates you have done, you just lose any data etc on the watch - so make sure that you sync prior to doing this step. Once you have done it, you will have pair the watch to your new phone, which will initiate the whole set up process again. If you have correctly set yourself up most if not all your details should be backed up and should come through when your set up. All you should need to do is install any apps that you previously installed and want to keep on the watch.
