BTRFS & Timeshift selected snapshot device is not a system disk

EDIT: Timeshift was just not worth it, snapper+btrfs assistant do what I need

I recently converted an existing ext4 install to a btrfs install, and everything went smoothly. However, I cannot get timeshift backups to work. I am also using systemdboot rather than grub if that matters, here's everything I can think to include to help diagnose the issue. Anything would be appreciated, have to be missing something.

Timeshift

 [jonah@arch] ~ ¥ sudo timeshift --check verbose
Using system disk as snapshot device for creating snapshots in BTRFS mode
Mounted '/dev/nvme0n1p1' at '/run/timeshift/3961/backup'
Weekly snapshots are enabled
Last weekly snapshot not found
E: Selected snapshot device is not a system disk
E: Select BTRFS system disk with root subvolume (@)

Subvolumes

 [jonah@arch] ~ ¥ sudo btrfs sub li /
[sudo] password for jonah: 
ID 448 gen 4637 top level 5 path @
ID 449 gen 4637 top level 5 path @home
ID 450 gen 4496 top level 5 path @games
ID 451 gen 4496 top level 5 path @music 

subvolume show root

 [jonah@arch] ~ ¥ sudo btrfs subvolume show /
