For me, the computer is visible on my phone, but it always tries to connect and fails after some time.

I have successfully completed a transfer from the computer to the phone, but not the other way around.

Is there any way to help with debugging this?

Phone:
Motorola Edge 50 Ultra

Computer:
ASUS M5406WA
NixOS Unstable
App installed through Flatpak
App version v0.3.0
