A21s disconnects from Garmin 235 every time the screen is switched off. No power saving options on the garmin connect app. Few people on the Garmin board with same issue. Have seen someone with a XI band also having the issue on reddit.
Bluetooth stays connected to car audio when screen off which suggests phone is putting Garmin app to sleep even when asked not to.
