Is your service of type oneshot? I.e.

[Service]
Type=oneshot

What's your timer set to? E.g.

[Timer]
OnBootSec=
OnCalendar=Mon *-*-* 00:00:00
Persistent=true

For an example, see https://blog.christophersmart.com/2021/05/23/auto-update-pi-hole-with-systemd-timer/ 

Also, do you need to enable linger for your user?

sudo loginctl enable-linger "${USER}"

-c
