miband

After updating to Android Q and MIUI 11, my Bluetooth started behaving weirdly. I even went a great long way to downgrade my phone back to Android 9 but still no avail. My Bluetooth forgets my last paired device (keeps asking for password of my car's bluetooth everytime I shut the engine down)...

When clearing the cache/closing all apps with the push of the button, my Mi Band 4 gets disconnected. I have to re open Mi Fit app, wait until it pairs together and that's when my band will connect. Also when I turn of the bluetooth and turn it back on, I have to manually open the app once again...
