Mi band 6 "waiting for connectivity" for both "notify for mi band" and "mi band tools"

I have tried setting up both mi band bridge apps (separately), and they both managed to record live accelerometer and heartrate data.

In each app, I have checked that sleep integration is enabled.

I bought the pro version of all apps, including sleep.

However, whenever I try to test sensors or start sleep tracking, I am stuck for a minute on the “waiting for connectivity” screen. After the timer, sleep defaults to accelerometer data.

Version of Sleep as Android: 20220118

Oh, and for the phone, Samsung s10
