Phone Bluetooth pairs with Pi 4 then disconnects permanently

[areed]

[b]Background:[/b]
I am trying to connect my Android phone to a Raspberry Pi 4B, with the intention of sharing the phone's internet connection via Bluetooth tethering. The Pi has a new, up-to-date installation of Arch Linux ARM, with bluez, bluez-utils and tmux installed, and I am interacting with it via the GPIO header UART connection.

[b]Replication:[/b]
- Boot the Pi and log in via serial console
- Open tmux
- Start the Bluetooth daemon in debug mode: #/usr/lib/bluetooth/bluetoothd -d
- Start Bluetooth monitoring: #btmon -w btmon_log
- Start bluetoothctl: #bluetoothctl
- Make the Pi discoverable: discoverable on
- Scan for devices on the phone, select the Pi and confirm the pairing on both sides
- The phone will now pair and connect, then disconnect after a few (~3-5) seconds
- The phone will not reconnect to the Pi even if explicitly told to do so,

[b]Observations:[/b]
I cannot see any obvious errors in either btmon or bluetoothd log output. As far as I can see, after a few seconds of sitting idle a disconnect command appears stating "Reason: Remote User Terminated Connection (0x13)" but I have no idea why. I've not had any luck searching for this issue online either, can anyone help me to understand what is going wrong here?
